I was advised to uninstall and re-install Reader 10 to "solve" some iss
ues. I'm running Windows 7. The uninstall seemed to go fine, but
I can't re-install. I see an error message from "UI_ReaderInstaller" that says...
"only a single instance of this application can run." What's wrong, and how do I fix this
so I can re-load Reader 10?
