I've installed Java SE Development Kit 1.6.0_31 32bit on Windows 7 64bit system, but this installation messed up my system, e.g. when I start Google Chrome I get error

Your preferences can not be read

Visual Studio 2010 after launching shows error that

The Application Data folder for Visual Studio could not be created

The shortcut to the Downloads folder in Windows Explorer no longer works. BTW this is pretty clean install, on other occasions after Java installation I had problems like this http://forums.techguy.org/windows-vista/808717-solved-c-windows-system32-config.html

Is there a way to install Java SDK without messing up Windows 7? Or maybe this mess can be cleaned up after installation of Java, but how?

  • I restored my system, now I want to know how to install Java without messing up my system again. – robert_d Mar 21 '12 at 23:00
  • Your question didn't state that you restored it – and you reported the error messages in the present tense, which is why I guessed they were still there, sorry. – slhck Mar 21 '12 at 23:03
  • java should NOT have done this. I dont think this is Java's fault. It sounds like you killed your %appdata% folder – Simon Sheehan Mar 21 '12 at 23:14
  • I have this problem always after installing Java, be it JRE or Java SDK, version 1.6 or 1.7. – robert_d Mar 21 '12 at 23:31

Use System Restore to restore your system to a date prior to your installation of Java.

  • I know that, I want help on clean installation of Java. – robert_d Mar 21 '12 at 22:58
  • Just install the latest 64bit version. I have it installed properly on Windows 7 Ultimate 64bit – Traveling Tech Guy Mar 21 '12 at 23:14
  • Which version have you installed? I had the same problem with latest version of Java 1.7 64 bit. – robert_d Mar 21 '12 at 23:33
  • I have 1.6.32 64bit. I have no problems with either Chrome or VS2010. And by the way, both do not rely (and in the case of VS even use) on Java, so I don't understand what exactly caused your issues. – Traveling Tech Guy Mar 22 '12 at 1:34
  • Issues are caused by piece of crap Java installer which messes up Windows 7 configuration, this is the only program that I have such problems. – robert_d Mar 22 '12 at 11:32

I've resolved my problem. I had to change Region and Language settings to English (US). Previously I had mixed English and metric settings. BTW if you are going to use Adroid SDK, you have to install 32bit Java - stupid Android installer won't find 64bit Java.
