Comment 73 for bug 1074260

I am trying to run:
http://<email address hidden>/try-comm-central-win32-debug/thunderbird-19.0a1.en-US.win32.installer.exe

I am using Win7x64. When I attempt to start Daily, I get the following error:

"The program can't start because MSVCR100D.dll is missing from your computer. Try reinstalling the program to fix this problem."

According to this thread:

It sounds like this is some debug library/DLL provided by Visual C++ -- do I need that?
