I just installed a fresh copy of Windows 7 and I figured while I was upgrading I might as well take the opportunity to also switch from VS2005 to vs2008. However when I try to build my app I get a linker error...

Error 528 fatal error LNK1104: cannot open file 'mfc80d.lib'

I did some research and it turns out this is because I'm linking to a 3rd party DLL and the lib file they provide was built with vs2005. I talked to the vendor and they said that they have no plans to upgrade to vs2008 so there is no chance for me to get a vs2008 built lib.

Is there any way around this? Are there any ramifications for having mixed code like this for the release build?

I'd rather not go back to vs2005 if I don't have to because I remember what a pain it was getting it to run correctly under Vista and I don't want to hassle with that again if I don't have to.

Thanks,
Dan
