File Associations Lost for Office 2010 Documents

Posted on 2012-04-09
Last Modified: 2012-06-27
One of our users cannot open Office Documents (Excel, Word) through double-clicking the file. The icon on the desktop appears "blank" and double-clicking results in a "Which Program Do You Want To Open With" dialogue. Strangely, Reader is the only program that appears available.

Browsing to the correct program file: (Program Files (x86)\Office 14\Excel.exe) does not work. Repairing & Reinstalling did not work.

If she opens Excel / Word first and opens the file through the program, the file will open properly.

She is using Office 2010 and Windows 7. Thank you.

If the EXE file association fix doesn't alleviate the problem, you may want to consider dropping back to an operating system snapshot prior to when the problem started:

If still no good, try a different user profile. If it's only her profile, coinsider to (backup and) delete and recreate her profile.

Has the file extension been dropped from the file name?  i.e.

"document.doc" renamed to "document"

if so, simply rename with the correct file extension.  If you don't know the correct file type, use the following site to determine it for you:

@Run5k - sorry if I'm missing something. There is no xls, xlsx, or doc, docx extension listed on that page..?

@Aur or Run: System restore did not work :/ Thought for sure that would do it.

@McKnife: Thanks! Deleting / recreating the profile worked!

Ecshelpdesk, I'm certainly glad that your problem was solved but normally you can fix the file associations with needing to delete the entire profile.

I think you may have accidentally misinterpreted what I said.  I specifically emphasized that you should "restore the default EXE file association" on the page that I listed, not the ones for the various Office file types.  It sounds like something changed the default executable file type association within that profile, and I'm fairly certain that would have alleviated the problem.

As a precaution, you may want to run a quick scan with Malwarebytes, also.

Ah...that makes a lot more sense. Thank you. And I'll run that scan :)

Glad to help.  Once again, I'm rather certain that would have fixed the problem without needing to backup the important documents within the profile, delete it properly, and then recreate it again.

In the future, I will ensure that I phrase that solution a bit differently to avoid any further misunderstandings.
