Topic Starter	Topic: Completely broken Java JVM
Foo Timed Out Joined: 02 Aug 2000 Posts: 38064	Posted: 10-19-2011 12:11 AM                    Back in the UK for a few weeks and using my dad's PC, but as with all family PCs it's horribly broken and I had to remove toolbars etc. One thing I can't seem to fix is Java. Upgrading or uninstalling produces the following error: I've attempted to remove it manually and by using JavaRA, but it's still showing in add/remove programs and still not functional in any way. I've also tried installing the 64-bit version but I think the broken one is interfering with that in some way. Any ideas? The program files folders for java are totally gone, and most of the reg entries are too, but they still show in add/remove programs.

The MSI is probably trying to run something in regutils.dll and failing because the file's not there. You could try finding the appropriate entry (look at the DisplayName to figure out which program's which) in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall", backing it up to a .reg file and then deleting it - then see what happens when you try and install the latest version. It might be worth having a google before doing that - if you back up the registry then there shouldn't be any gotcha's, but there might be another key that i'm forgetting to mention (maybe the upgrade code needed deleting as well, i can't remember). edit, looks like it is just the one key: http://support.microsoft.com/kb/310750

After doing that I could install a fresh 64-bit JVM, and it appears to be working as expected.

My computer is full of information and extremely slow. While looking for old files to delete, I came across some old Java updates that were taking up 400 MB of space. Is it necessary to keep all of them or just the newest one for Java to work? _________________ movers in nyc send text message online Last edited by chorinne on 08-07-2012 01:43 AM, edited 2 times in total.
