When running the 3.11 setup program underi WIndows XP with NTFS partition I get a warning about 2 running process in memory: SUBST.EXE and JOIN.EXE. If I press C to continue anyway, DOSBOX closes completely.

I don't think I can remove the EXEs from memory because XP does not even show them in the task manager, they must be hidden.

If I can't solve this, where could I get a Windows 3.11 OS already "installed"?
