I recently built a new computer and installed Windows 7 Ultimate 64bit.
I have had absolutely no issues except with Java. The first install that I tried was the latest 64bit version of Java and it crashed right after install. I then tried uninstalling and installing the 32bit instead but same problem.
I have tried installing several older versions both 32bit and 64bit and they crash as well, always uninstall the old before installing the new. Tried a different install directory and that didn't work.
When I install Java it crashes right after the install. I can't even open the applet in the control panel. Here are the details from the application event log:
