Thank you again for your reply. I will try to explain again: I AM a system administrator and a tech support for the domain. The error message is a common one that we get when trying to uninstall software that has registry keys in the various install/uninstall paths. We get the same error with Acrobat Pro 8 and a few other applications sometimes. The solution for all of those is to go into the registry, and remove keys from the install/uninstall paths. Acrobat, TechSmith, Appligent, and other companies were immediately helpful and provided the information I requested. I assumed I could get the same quality of assistance here.
Cineplayer is a core app on one of our system builds - users cannot watch DVD's on their computers without it. I have the installation software and and I have tested the same installation files on other systems with the same build with no errors. I have also gone through the install/uninstall registry paths looking for entries with Cineplayer and Roxio, taking care to back up the registry, of course.
I understand that 'if cineplayer did not install, there is no need to uninstall it' but whenever anyone (including our automatic software distribution program which uses SYSTEM rights) tries to install it we get the error message. That is why it was escalated to me. I spent several hours trying to figure it out on my own but was unsuccessful. Hence this post.
I will politely ask again and pray that someone can help me otherwise my only other option is to re-image the machine:
"What are the registry keys needed to manually remove Cineplayer 2.3.1, please?"
