It is not included in the links provided when installing Upp, I left the Redistributable selected but it was not in there, I may be wrong on this.
I added this to my PATH:
C:\Program Files\Microsoft Visual Studio 9.0\VC\redist\x86\Microsoft.VC90.CRT
depends.exe finds MSVCR90.DLL but "java HelloWorld" now gives this error:
R6034
An application has made an attempt to load the C runtime library incorrectly
I tried copying MSVCR90.DLL to the same directory as HelloWorld.dll and got the same error.
