I have renamed msi.dll to msi.old. But now this is giving error, because of this I cant able to open microsoft office. now again i want to rename it as msi.dll.

But I don't know the place where it lives. Where is the msi.dll? How i can rename it again.

First time renaming what were i did that with help of some notes but i not have them now

I have performed a search on Windows (search string was *.old and msi) but this did not located msi.old

Try to repair Office first. If that doesn't help, uninstall and reinstall as Dave suggested. – Karan Nov 23 '12 at 21:54

There are many places this could be, on my PC a search for msi.dll returned 2 locations:


However, if you have named it msi.old, you could try to search for it on your machine? Click start -> Search.

Type in msi.old and search for it! Or, based upon your comments, search for msi. (include the period ".").

Worse case, re-install the program.
