MSVCR71.dll error msg

I am receiveing a MSVCR71.dll error msg "This application has failed to start because MSVCR71.dll was not found.  Re-installing the application may fix this problem."  This popup started about three weeks ago on about 9 out of 94 selected computers with the same configuration.  Your assistance with the resolution will be greatly appreciated.

Download details: Visual C++ 2008 Redistributable Package (x86)
Basically, this is either a single file missing or the entire Side by Side assembly is missing.....

Maybe an update triggered a removal or a deletion of one of the assemblies.....

See ifyou can set the filter to include "Process Name is YourApp.exe to INCLUDE", and then set the filtering to highlight "Not Found"

Look for c:\Windows\SXS as the path not found.... These SXS assemblies can be copied from one machine to another.....

download fresh copy of from
save it on your C:\windows\system32 directory
now run the command by clicking START --> RUN
regsvr32 /s MSVCR71.dll
or regsvr32 /s "C:\windows\system32\MSVCR71.dll"
Restart computer

Think you need to get to the root cause though... 9 out of 94 systems come up with a single missing file, you need to see what was deployed/installed/updated, to see what might be stepping on it.....

I agree, there was no schedule to push updates during this period.  This will have to be researched find the root cause.  Thanks for your comment/suggestion!
Maybe a virus infected the file and realtime protection quarantined it? Just an idea.
