Question

I get this error whenever I try to start World of Warcraft, Audacity, or Blender. What does it mean, and how can I fix it? This is on Windows 7 64-bit.

This was all I could find in the event log:

It looks like all it logged was the appearance of the dialog box.

Answer 1

That error is often caused by a faulty set of older (2005) C++ libraries.

Try removing and reinstalling them.

You can get an updated version from MS here: Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package ATL Security Update (or the original 64-bit version here).

Edit:

I'm still pretty sure this is a Visual C++ runtime library problem. Perhaps it's not the 2005 version specifically in this case.

Check your Add/Remove Programs and determine which, if any, MS VC++ runtime libraries you have installed. And, as before, uninstall and reinstall them.

Here's some links to help you get them:

• Microsoft Visual C++ 2008 SP1 Redistributable Package (x64)
• Microsoft Visual C++ 2010 Redistributable Package (x64)
• Visual C++ Redistributable for Visual Studio 2012 Update 1
