I had the following version of Java installed: 1.6.22. There is an update which I try to install but W 7 gives me a notice that the application wasn't installed correctly. When I tried to install with the "recommended settings", nothing happened at all. My fierst step to overcome this was to completely uninstall the installed version which worked alright.
I shut off the laptop and then restarted it, went to Java and downloaded the setup exe, but this resulted in the same issue. the next step was to restore to an earlier point which worked. In the Control Panel the Java icon was back but would not open at all. The next step was to uninstall the above version with Revo Uninstaller. After this restarted and tried again to install and this time it did not work at all. Now, I am without Java. What seems here to be the issue? I have to mention that I upgrade the laptop from VISTA SP2 to Windows 7 already in November 2009. Since then I updated Java about twice without a problem.
