I am having Windows 7 64 bit RTM installed on it Office Mondo TP 32 bit (64 bit version doesn’t work correctly with the Windows Mobile Device Center) Along with VS2008 & VS 2010 Beta 1.
I have found a post by Gary Pretty (Thank you for that Garry!) that solves the problem by replacing the msvcm100.dll installed with Office Mondo with the one installed with VS2010 originally.
The problem is that if you’re having a 64 bit operation system, you don’t/shouldn’t replace the file in the system32 folder, instead you should replace the one on the “SysWOW64” folder.
Enjoy!
