Windows 7: can't open (excel) files

21 Apr 2010   #11

Windows 7

I had the same issue but unchecking 'Ignore other applications that use Dynamic Data Exchange (DDE)' resolved the issue. I am using Windows 7 and Excel 2007. I believe the issue occurred at the same time I installed AVG antivirus.

You can get to that option in excel by clicking on;
-Office 2007 icon at the top left in excel
-Excel options at the bottom right
-Advanced from the selections on the left bar
-Scroll down to General
- Untick 'Ignore other applications that use Dynamic Data Exchange (DDE)'

Hope this helps as I tried to be as detailed as possible

This gets my vote.

About DDE: if you turn that off, you will lose some functionality between Office apps.

A little additional information on this, this can be controlled by GPO or a registry change. This setting is also known to cause Excel and other documents to not open by double clicking them. But opening the application by means of a start menu or shortcut to the application and then doing a File Open for the document will work. As a fix if Unchecking the box isnt working for you (as some have reported that issue on various sites) changing the registry or setting/modifying Group Policy can resolve this. See attached screen shots, this works for all versions of Windows and Office 2007 or 2010. The registry entries will only exist if a Group Policy Administrative Template was used. But if it isnt there, you can create the keys and entry and it will resolve the problem. Big important note on this policy as you will see in the screen shot of the registry, the registry setting is opposite to what you are use to most likely. In most cases a "0" is off and a "1" is on. This is not the case here, "1" is off and "0" is on. So as in my screen shot, this will turn off (or in other words Uncheck the box) and thus allowing your application to work. Hope this sets some light on the subject for those trying to resolve their own issue. Best of luck.
