Error 1500 stops Messenger install



When I download WINXP Messenger and start the installation process, it stops
with a Error 1500: Another installation is in progress. You must complete
that installation before continuing this one.

I'm not installing anything else. I rebooted my computer and still received
the same message.

Any other ideas on how to install this product?

Greetings Mike,

Assuming you're familiar with editing the registry, navigate to:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Installer\InProgress within the
registry and delete the InProgress key.

Then do the same for HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session

Then if at least one of these existed and you've now removed, give it a shot again.

Jonathan Kay,
I didn't have either of those folders or values present on my registry. Is
there anything else that I could try?
