Excel 2007 corrupt / encryption problem

[matthewinuk]

I created some excel files and used their encryption in office 2007.

Eveything was fine, but one day I tried to open them and got an error message saying "the file is corrupt and cannot be opened".

the file is stored on a remote drive at the university server. I can open it fine from everywhere except the one computer I have at my desk. If I go into the university library for example, I can open it there.

I decided to try and make a blank excel file and encrypt it. When I try to save the document to the remote drive it comes up with the following error "Microsoft Office Excel cannot access the file 'C:\Documents and Settings\[my username]\Local Settings\Temporary Internet Fiels\Content.MSO\33C63000" Which is very strange.

If I try to save directly to the computer's desktop I get the following error;

"Microsoft Office Excel cannot access the file 'C:\Documents and Settings\[my username]\Desktop\1CF83000"

I wonder whether there may be a registry error or something? Who knows? Prehaps you can help. It would be very much appreciated.

I have the answer

I had the same problem. I couldnt believe how little internet talk there is about this. Its odd, very few people seem to have experienced it. Anyways, I did. It also occured for me in my other office apps. After much much hair pulling I fixed it. I had created a new user account on the problem PC and for that new user I found the problem didnt occur. I then realised it had to be either a user registery or user files issue. As it turns out its an issue with files under Application Data. Goto: C:\Documents and Settings\YOURUSERNAME\Application Data\Microsoft\

Its the Crypto directory. Just rename it when no office app is open. Then reload your excel or word and try again. If that doesnt work also try the same procedure with Credentials and CryptnetUrlCache folders but I believe just the Crypto should do it.
