Windows 7: Cant Install Messenger 2009 or 2011 - hr:0x80070643 error and others

Cant Install Messenger 2009 or 2011 - hr:0x80070643 error and others

Hi, Im J.P., I need your help

I have a huge problem with Messenger. I cant install the 2009 or 2011 version.

The situation:

Time ago I had the Messenger 2009 and all worked perfectly but I wanted to try the latest version (Messenger 2011). With the program "Your Uninstaller" I tried to uninstall the Messenger 2009 but I got an error that I dont remember. The program "Your Uninstaller" is a software that, when you finish to uninstall a program, Your Uninstaller search for the left registry key and delete them to keep the registry in good health. Well, I got an error when I uninstalled Messenger 2009 but I accept to delete the left registry keys via Your Uninstaller. After that, all my problems started: when I tried to install the Messenger 2011 I got an error hr:0x80070643.

After that, I tried to install the Messenger 2009 again but I got this errors:

- Microsoft Application Error Reporting: aborted:0x80004004
- Microsoft Visual Studio Runtime: aborted:0x80004004
- Windows live upload tool: aborted:0x80004004
- Windows live sign-in assistant: failed_prior_task:0x80004004
- Installer: failed_prior_task:0x8004004
- Microsoft Choice Guard: failed_prior_task:0x80004004
- Windows live communications platform could not open key: UNKNOWN\Components\9ADA8EA9BDDCBA\940E57139A9FD3A4 F891CAF90B54411D. Verify that you have sufficient access to that key, or contact your support personnel. hr:0x80070643

What can I do? I tried alot of things but I cant make it works. I cant try a earlier Restoration Point because this happened some months ago. Any help is appreciated. Sorry for my english, is not my native language. Thanks in advanced.
