I have windows xp in a partition and recently i installed windows 7 in another partition. From then there is this problem with windows xp, exe files are not opening, when i click on exe files, open with window pops up... Also my antivirus(mcafee 8.5i) is completely disabled in xp. Is all this because of windows 7? Please help me, how to fix my xp again.
