Microsoft Office stopped working properly

Question

I used the following link to include a new language and Word stopped working properly

http://office.microsoft.com/en-us/word-help/enable-editing-of-multiple-languages-HP003084566.aspx?CTT=5&origin=HP003089543

I am using Windows 7 and tried to return to a previous stage but the problem remained. I tried to uninstall and reinstall Office but got the following error message:

E : \Homestudent Fr. WWW\OSETUP.DLL digital signature does not validate or is not present.

Excel stopped working as well. Is there a way to fix this issue?

Answer 1

There are some working solutions to this problem on Microsoft Technet Forums. Have a look.
