Vista - Windows Live Installer Error 0x80070643

Trying to update Windows Live Messenger on a Vista Computer running Windows Live Messenger version 2008. I get notified that a new version of Messenger is ready to be installed. When I run the update using the Windows Live Installer program, it completes the install 100%, then proceeds to rollback the entire install. It gives me error #0x80070643, and says there may be another installer running at the same time (there is not). This has happened each of the 3 times I have tried to run this update.

Another error I am getting from this Windows Live Installer:"a network error occurred while attempting to read from the file c:\windows\installer\photolibrary.msi"

Searching on that error message, I found this: https://www.microsoft.com/communitie...r=US&sloc=&p=1

But nothing here has helped either....
Any ideas?

thanks in advance...

Here is Phat94gt's post from the MS forum:

Actually, I found a solution that worked for me:

1. Manually uninstall all the Live applications, except the Photo Library.

2. Download Windows Live Photo Gallery Beta from
Installing/uninstalling Windows Live Wave 3 beta applications - Windows Live

3. Move the downloaded PhotoLibrary.msi file into C:\Windows\Installer

4. Run the msi

5. Run the windows live setup and install / update any Live programs

This did the trick.
