IE11 isn’t compatible with Win7 unless you turn off some Win7 features. I tried installing twice and gave up on it.

Odd, I'm using Win7 and IE11 right now and didn't have to turn off anything.

You may not have had them turned on already or you didn’t notice they were turned off after the upgrade because you don’t use them. At least Microsoft documents the incompatabilities so you know it is supposed to be that way (IE11 is designed for Win 8 and not Win 7).

Same here. I’m running Windows 7 & IE11 on a 64 bit PC and on a 32 bit laptop without any problems.
