XAMPP 1.7 - Apache not working on windows7 64 bit.

I tried installing XAMPP with xampp-win32-1.7.4-VC6-installer . I was not able to get apache working. The apache started and then stopped after 3-4 seconds.

I tried various things like running the setup with vista compatibility and as administrator. But nothing worked..

So the best way i found was to fix the issue using old version of xampp i.e 1.6 .
The old versions of xampp can be found at:

http://cdnetworks-us-1.dl.sourceforge.net/project/xampp/XAMPP%20Windows/1.6.8/xampp-win32-1.6.8-installer.exe

now it works just fine :)
