I have a nasty problem that occured when I uninstalled a nvidia system utility.
The utility told me it needed to stop some running applications and I said OK. Avast then popped up and said that a program was attempting to shut it down . I said OK. From that point on avast would not start anymore on reboot or manually.
Avast reports that msvcr71.dll is missing.
I cannot uninstall Avast using the control panel, or update or repair it (same error) so I downloaded your utility to remove ASvast in safe mode.
This went OK. I then attempted to reinstall avast which went OK until it asked me to reboot. It then gave the same error message all over again. Can’t find msvcr71.dll.
I placed copies of this file into c:\windows\system,c:]windows\system32.dll,c:]windows\syswow64 with no change.
I rebooted into safe more and placed this into the avast directory. Still no change.
I cannot get avast to work. (I’ve used this for a long time)
System Vista Ultimate 64bit.
Can you please help?
Will any of these links help?

Thanks for responding!
Yes, I have checked out all of these links and tried all of this, and none work.
Do you know what size and date this file has to be? Do you know where your software looks for the file on Vista64?
Is there another file that might me missing that the software doesn’t report?
I do know that when you install avast you do not put this file in the avast directory.
Do I need to reinstall the MS C++ redistributables?
Is there a log that can giver me more details?
Thanks
Their software… I’m an user like you…
Please, post the last 200-250 lines of avast log: C:\Program Files\Alwil Software\Avast4\DATA\log\Setup.log
I’m not able to answer the other questions… Sorry.
Thanks. I will look at the log tonight when I get home.
Ok. We’ll be here to help 
Was there any resolution to this? I have the exact same problem: Windows Vista 64-bit, Avast barfs on startup complaining about missing msvcr71.dll. I know that I perhaps missed a window to re-register the product. I cannot uninstall/reinstall due to this problem. here is an excerpt from the log:
