I have the same problem
I did a factory restore on my HP win 7 64 bit laptop
internet explorer 8 worked fine
used windows update checked everything
Internet explorer 9 got installed
only the 64 bit version works
-( prior to the factory restore ie9 worked fine)
did everything suggested in this thread
- reset internet options
- verify i did not have a proxy activated
- verified I did not had an asus
driver interfering
- did the sfc scannow thing in an elevated command prompt
- did the netsh thing in an elevated command prompt
if I open the ie 9 32 bit version, it opens SLOWLY you can do a thing or two and then it freezes and/or crashes
if I uninstal ie 9, ie 8 works fine
i upgrade and the problem comes back
suggestions?
