FB 4.5 will not start on Windows 7 64 bit

I installed FB 4.5 on Windows 7 and when I try to start it I get this error:

C:\windows\system32\MSVCR71.dll is either not designed to run on windows or it contains an error....

I tried to run in Windows XP sp2 compatibility mode and I get this error:

Failed to load the JNI shared library "C:\Program Files(x86)\Adobe\Adobe Flash Builder 4.5\jre\bin\client\jvm.dll".

Any ideas on what to try next?

Thanks,

Ben
