Yes, I know... I could set up a virtual machine running XP. Unfortunately our build environment is such that we need to be running VC2003, 2005 and 2008 concurrently and it would be much more convenient if I could run 2003 natively on Windows 7 for the few projects we have that require it.
I realize some things may not be available in the IDE, but I was able to run 2003 under windows Vista and if I could get the same base level of functionality under Windows 7 I would be extremely happy.
Right now I get an error opening the *.pdb file when I compile after switching vc2003 to run as Administrator under compatibility mode for XP SP 2.
Thanks!
Give XP Mode a try if you can't get it to run natively.
