How to fix missing MSVCR71.dll problem in Windows
I am using Windows 7, and I’m lacking MSVCR71.dll which is Microsoft Visual C Runtime library when using sendmail, the PostgreSQL PHP connector and curl. The MSVCR71.dll is probably bundled with .NET Framework 1.1 or something, but I couldn’t get those to install successfuly.

The program can’t start because MSVCR71.dll is missing from your computer. Try reinstalling the program to fix this program.
So how do I solve it:
- Download MSVCR71.dll from dll-files.com. (It is free.)
- Unzip…
- Place MSVCR71.dll into C:\Windows\System32 or C:\Windows\SysWOW64 if you using a 64-bit Windows.
And sendmail now works for me already in Windows 7.
By the way, I only tested this in Windows 7 64-bit. I assumed it would work for other versions of Windows. I would appreciate it if you could feedback to me if it works on your version of Windows.

Yep I just tried this with windows 7 32bit and it solved my problem too..
Thanks a lot dude!

Thanks for the tip, this solved my problem! For those that don’t trust using a library you find on the net, I found a copy of the msvcr71.dll library sitting in my MS SQL Server folder. On my system, it was at: C:\Program Files\Microsoft SQL Server\80\Tools\Binn

Thanks a lot for this info! I found the dll file, but wasn’t sure where to put it on my 64-bit Win7 OS. This helped me out a lot, and eased concerns on where I found the dll. (It was the same place you linked).

Its not letting me unzip the msvcr71.dll in either C:windows/system32 or C:windows/systemwow64 it says that access is denied and that I require administrative privileges. I am trying to get this to run on a personal laptop, no network, and there is no loggin screen when I start my computer. Help Please.

This is what I would have figured to make things work. HOWEVER… :/ It doesnt work for me. I placed the file there, even restarted windows a few times… and nothing. The error is still there. I am just starting to use Windows 7 Ultimate and since I abhore Microsofts Internet Explorer, I NEED this to work, so that I may use my alternate browser choice.

There is a popular winamp plugin that provides lyrics. It apparently needs the files this article addresses. When I found the msvcr71.dll the lyics plugin started to work properly. I am running 64bit Windows 7. Thanks for the help!

AOL 9.0VR wouldn’t open and gave me this fault. I had already copied this dll into Windows/ system and it worked but kept disappearing of it’s own accord making me paste it back in daily. I put it in Windows SysWOW64 and that did the trick. Thank you
