MSVCR90.dll is missing

[Mr.Mike]

Hi all,

This one has me stumped. My client has a Windows 7 OEM machine that a Trojan virus I removed three weeks ago. Yesterday, when he tried to use MS Office 2010 Home & Student to run Word, he gets: "...the program can't start because MSVCR90.dll is missing. Try reinstalling the program to fix."

I've tried uninstalling/reinstalling Off. 2010, and tried re-registering all the .dll files using this method. No Joy. Searching this forum, no mention of MSVCR90.dll is found.

Searches elsewhere indicate only that it has to do with Microsoft Visual C++ 2008 Redistributable and if you uninstall and reinstall that, that should fix the issue. Nope.

Microsoft says that if Microsoft Visual Studio Tools 2005 for Office Second Edition Runtime is installed, then uninstall it. That is not loaded on my client's machine.

As Window Pros, are you familiar with this issue and is there a solution besides attempting a repair/reinstall of the OS?

Thanks in advance for your comments/suggestions/help

Is this thing running Symantec Endpoint Protection (or was it running that) ?

I've got a simple question, I hate too even ask it because I know you've already tried it but I didn't see in your post, have you tried replacing the .dll file from another win 7 machine? Couldn't the Trojan virus you removed might have damaged the file and that .dll file is not being removed with uninstalls because its being used by different programs?

Thanks for that NYJimbo. I'll check that out. It wouldn't surprise me since Symantec seems to be a frequent culprit. I'll post back tomorrow morning after getting back to that machine.

Interesting. No. I haven't tried simply copying the file from another win 7 machine, but thanks for the benefit of the doubt. I figured the uninstall/reinstall would have fixed that. Looking at it your way, that seems entirely possible. I thought if a file is damaged/corrupted, then it couldn't be used by any program. If the file was altered/corrupted, say using two number one's rather than two "LL's" in the .dll extension, I can understand that it could be used.

I will follow up in another post here when I've checked that out.

Thank you BT.
