Delete EXD files to fix “Object library invalid” error

We have a Microsoft Word template that contains macros, which was working fine but all of a sudden in the last few days, whenever you invoke the template you get the following error:

Word has encountered a problem.

Word has encountered a problem.

If you open the template file instead of invoking a New document from it, you get a more detailed error:

Object library invalid or contains references to object definitions that could not be found

Object library invalid or contains references to object definitions that could not be found


This was obviously due to a change in our systems. After googling awhile, I found this article which explains that the error can happen after installing a certain Windows update:;en-us;932349. The update installs new versions of certain Visual Basic 6.0 Runtime files. The article provides a link to a cumulative update rollup which I tried, to no avail.

Upon further investigation, I found that the files had been updated fine. However, there is a corresponding EXD file that is created for each of the runtime files, when you use the controls provided by the runtime files in the Visual Basic designer. When the runtime files are updated, these EXD files are now invalid and hence this error occurs. To fix the error, you need to delete the EXD files and they will be re-created as needed.

These files should be located in the folder: %APPDATA%\Microsoft\Forms\

On Windows XP, it is usually located in:
C:\Documents and Settings\%USERNAME%\Application Data\Microsoft\Forms\

And on Windows Vista/7:

EXD files

It was easy enough to fix for myself, but others were having this problem – so I made a script that given the username deletes the files. I had users run the script (you can post it as a link on a webpage and as long as you use Internet Explorer and low security settings it can be invoked from there):

// Function to delete EXD files from user Application Data folder
//     This is to resolve an issue with Word VBA macros that use VB runtimes, which the EXDs point to
function deleteEXDs(){
    var strToPath = "%appdata%\\Microsoft\\Forms\\";
    try {
		var fso = new ActiveXObject("Scripting.FileSystemObject");
		var shell = new ActiveXObject("WScript.Shell");
    catch (err) {
        alert("Could not create ActiveXObject.\nThis script should be run from Internet Explorer, \n" + 
		      "with low security settings (e.g. Intranet or Trusted Sites).");
    try {
		var appdata = shell.SpecialFolders("AppData");
		var strToPath = appdata + "\\Microsoft\\Forms\\";
		var fldr = fso.GetFolder(strToPath);
		var noEXDs = true;

		for (var e = new Enumerator(fldr.Files);  !e.atEnd();  e.moveNext())
			if (fso.GetExtensionName(e.item()).toLowerCase() == 'exd')
				noEXDs = false;
				try {
					var filename = new String(e.item());
					alert('DELETED ' + filename);
				catch (err)
			        alert("Error - could not delete " + e.item() + ".\nDescription: " + err.description);
		if (noEXDs) alert('No EXD files found.');
    catch (err) {
        alert("Error - could not clean up EXD files.\nDescription: " + err.description);

Edit 26 Oct 2010:
Thanks for all the positive comments!

I noticed that this solution of deleting the EXD files is now also being mentioned in the Microsoft KB article:

Edit 1 July 2011:
Thanks to the comment below by Paul M Edwards, I updated the script to use the AppData environment variable, so it should now work with Windows newer than XP.

    I was getting this error message when trying to launch a custom vb routine in AutoCAD. I found the exd file in the forms folder just as your article describes. Now the error message is gone! Thanks Lessan, you are awesome!

    I have Windows 7 and have also recently installed Office 2010 as an upgrade from 2007. Where would the .exd files be in this case? Do you delete the .box files too or just the .exd?

    This was great advice! The “object library invalid” box was coming up every time I started or shut down Word 2010. I deleted the one EXD file I saw in the folder (MScomctlLib.exd) I left the .box file ( alone. Now no problems. Thanks!

    To Sarah above, you should be able to find the exd files under:

    C:\Users\Your User Name\AppData\Roaming\Microsoft\Forms

    Just delete the exd files, not box files.

    Thank the author again for saving our lives.

    Thank you! I have had this problem with Office 2003 for many months, without finding a solution, until now.

    I had three EXD files in there, and one was zero bytes in size. I also had the exact same error message when starting up and shutting down Excel. Fixing that involved deleting an add-in file (.XLA) in:

    C:\Documents and Settings\USER\Application Data\Microsoft\FormsExcel\XLSTART\

    The Add-in file was dated 2004, so I guess is was not the *source* of the problem, but it does make the startup error go away so I can work out what needs to be reinstalled.

    I have tried deleting all the *.EXD files

    Any other idea?

  45. Posted 2011/03/04 at 1:51 am | Permalink

    I have discovered that the Object Library Invalid error can result from another cause. I read these posts, and removed the .EXD files, and got no improvement. Then I went back to my code and examined it in detail. I discovered that I had a button called BudgetIndividual, with a procedure named BudgetIndividual_Click. In another module, I had a subroutine called BudgetIndividual. This caused no problems.

    But when I copied the BudgetIndividual procedure into the sheet module that contained the button with the same name, I got the Object Library error. This, as you may have noticed, is not an informative or helpful error message. And I have proven that it can have multiple causes. In this case, all I had to do was rename the procedure to BudgInd, and all was fixed!

    Great! Worked for me as well! I had Office 2003 and I upgraded “only” Outlook to 2010. After that I started getting the above error at start-up for Excel. After I read your article, I deleted the MSComctlLib.exd which was the only file in that path and then restarted my Excel. The error vanished and I also saw that there was a new file created by same name “MSComctlLib.exd”.

    Thank You So Much!!

    This is a great tip which has been very helpful.

    One addition I would like to make is that the following path will provide the correct folder location regardless of Windows version or username by using an environmental variable:


  62. Posted 2011/07/01 at 10:09 pm | Permalink

    Instead of “USER” in the paths, you can use %USERNAME%, i.e.:

    On Windows XP, it is usually located in:
    C:\Documents and Settings\%USERNAME%\Application Data\Microsoft\Forms\

    And on Windows Vista/7:

    You can save the script as a javascript file (e.g. script.js). If you then double-click on it it should work.

    You can also link to it from a web page, and if you are running Internet Explorer with low security settings when you click on the link the script will have access to the local filesystem and do what it needs to do. Of course, the low security settings should only be used in a protected environment otherwise it will expose you to dangerous scripts on the internet. So you would add only the webpage you have hosted it on (preferably on your intranet) to the Trusted Sites group, or something like that.

    Hi! I’ve received the same error, but with no previous Excel upgrade. I have been using Excel 2003 on Win XP for a while.

    Only see the error when I run a particular XLS that uses lots of macros and DDE to communicate with another application. The rest of the XLSs, even those with macros,work just fine. After I receive the error message, VBA Editor stops at the definition of a sub() function.

    Any ideas? I’ve tried already deleting the .EXD files, to no avail. Thanks!

    Thank you very much. I wasted 3 hours trying to find an answer for this problem. Google, bing, windows support, etc, and others and not even Microsoft support for office 2010 has a clear answer. I red several website but nobody gave me a simple answer the works, until I found your solution!!

    One suggestion would be to post your solution in youtube or other high traffic website, since I am sure there are hundres of people with the same annoying problem, that would benefit from your solution. Also Microsoft should issue a warning for that specific update so people do not update the one that installs new versions of certain Visual Basic 6.0 Runtime files.

    Thank you so much.

    I can’t say where I work, but our tech people were going to re-image my entire machine because of these errors! Wonder why they didn’t do an Internet search to find your simple & elegant solution!

    I used the manual method and this worked. However I wanted to save your script but I do not see what file extention this is supposed to be save as. It this a batch script or some other language?

    Thanks for the post and the help.

  105. Posted 2012/04/11 at 11:09 pm | Permalink

    You can save it as a .js file, as it is JavaScript (or JScript I guess).

    Just got this error after Windows Update installed various updates to MS Office 2007 and some system updates for Windows 7 2 days ago. Tried to restore the system to earlier time, uninstall recent updates a.s.o. Then I googled the text of the error message in Word and found this solution. It worked “from scratch”.
    Thank you very much for this help, as I was not able to find any solution around.

    I had to use this fix twice recenlty on a Windows 7-64 box with Office 2007 on it.
    Other similar computers did not have this problem.
    The only thing that make this PC different is that it has Exact Globe 2003 installed – Dutch bookkeeping software.
    I’ve added a short to C:\Users\%USERNAME%\AppData\Roaming\Microsoft\Forms on the user’s desktop so he can remove the offending template files himself next time this happens.

    Posted 2012/04/27 at 3:15 pm | Permalink

    There are no .exd files in my system, searched by file extensions. Also searched for the location mentioned by you C:\Documents and Settings\%USERNAME%\Application Data\Microsoft\Forms\, but my machine does not have Microsoft\Forms folders in AppData. It has the following folders – C:\Documents and Settings\jyarida\AppData\LocalLow\DataMngr and there is only 1 file in DataMngr it is {7CA1F051-A4FB-4143-B263-02B41E571EED}, not sure if deleting this would result in some adverse outcome, therefore I didn’t delete it. Thought if I run the script you gave may fix the problem from all locations (if not from the location you mentioned), can you please tell me how to run the script? Or, is there any other solution?

    Thanks a lot!

    What can I do? Please help me!

  205. Posted 2013/02/04 at 8:40 pm | Permalink

    If there are no EXD files and you are still getting that error, it may be due to something else. I think there are a few other reasons for the same error message to appear. You can try searching further on Google for these – I haven’t had any experience with them myself.

    I Lesson, after 4 years this post is still very helpful. My situation was: I have some excel macros with a date control (DTPicker) and yesterday i need to do a change in macro and this error appear (Object library invalid or contains references to object definitions that could not be found). So, this error was created because from last time that I use the macro and yesterday I installed a application that work with VBA and probably it change the file MSComCtl2 that change the MSComCtl2.exd out of date. so, for my situation you solution works well. After delete EXD files the error missing and the new MSComCtl2.exd was generated in profile path and now I can change may macro.
    Thank you for share the problem and solution .
    Best regards, Vitor
