I have two computers. A has 2008, 2010 and 2012 installed and in win7 64. B has 2008, 2010 and is XP 32. I upgraded the sln file from 2008 to 2010 on Machine A. When computer B tries to load the sln file in 210 it asks to upgrade the solution. This break the automated build process.
A and B both had the latest sp patches.
I looked at the sln file and see no reason for this behavior...
