Had Defender, updated, now error: MSVCR80.dll not found

[Guest]

I bought into OneCare. Later I got Defender. I think it was version 2. It
requested I update. I did so. But upon install and reboot computer now
reports error: MSVCR80.dll not found.

No attempts to reinstall work out.

Try this: Go to \program files\windows defender

and see if you have a file: MSASCui.exe.manifest

If so, delete or rename that file--the one suffixed "manifest"--not the
actual .exe file.

I had the identical error msg. I tried deleting the "MSACui.exe.manifest"
file. Didn't effect a thing, still get the error msg. If this board doesn't
get a fix by tomorrow, I'm going to import the old defender download from
another computer and try putting it back on. But something tells me that
probably will be a problem as well. This program has had issues since it
came out. It is a beta but ........

Removing that manifest file is the standard fix--but perhaps there's
something different going on. Have you tried a repair via control panel,
add or remove programs, windows Defender, change, update?

Can you tell from the error message what application it is that is calling
for the MSVCR80 file? I am recalling several threads here where specific
third-party applications raise this message after Windows Defender is
installed. The fix from the standpoint of those apps is to remove Windows
Defender. I don't believe that I have a resolution for this issue--which
appears to be an app compatibility or "dll hell" type issue--I believe one
responder stated that getting a copy of the named file in the install folder
for the third-party app fixed it for his particular case.

So--removing the .manifest file should fix this message if it is related to
execution of Windows Defender. However, if it's related to a third party
app, I'm not clear on how to resolve it, except perhaps removing Windows
Defender beta2.
