I'm stumped... I have figured out how to use SNMS correctly, as far as I know. The problem that I am getting is the "XPDNF20sp230sp235sp1.exe is a WXP only installer." I am creating the t-13 .7z to use in my new test xp cd. I think that the addon or addons that may be causing the issue are XPTSP and/or the MCE/7MCE addons. I'm positive that the program isn't recognizing the install as XP. I have also extracted the .7z and tried to just run the executable in a VM that included those 2 addons but it still would not recognize the os as XP. Now the funny thing is I compiled SNMS on the VM as an addon, extracted the .exe and ran it, and it ran fine. The issue is when I used the .7z file to build the xp cd again including the addons, during the VM install, again, it would not recognize the os as XP. Long story short, is there a way that I can force the installer to install os independent? I rarely install anything other than xp x86 so the os check for me is not crucial. Also, is it possible to add a switch in your bat or is there something that I can erase that can remove this os check?
