I am trying to un-install FrameMaker 2019 from Control Panel and I am getting the message "Administrator privilege needed to proceed with the install. Please click Retry to install again after providing the necessary permissions (Error Code 24)". I have also tried running the command listed here https://community.adobe.com/t5/framemaker/filemaker-2019-silent-uninstall/td-p/10454737?page=1 and get the same error. I don't care if the install is silent or not.
According to my search online Error Code 24 is that I cancelled the install, the user account being used is in the administrators group on the computer.
When "normal" uninstalls of Adobe apps fail on my machine, I use the AdobeCreativeCloudCleanerTool.exe, which you can search for online.
I ran the tool you mentioned and checked Add/Remove programs says that the product was un-installed but I am able to launch the application so obviously its not gone, now when I run the tool again it doesn't show up as an application that can be removed.
You could use a program like Revo Uninstaller to scrub the registry clean and remove any trace of previous installations. https://www.revouninstaller.com/ . I think the program is available as a fully functional trial version.
The software that I am allowed to install on our computers is heavily restricted so that is not an option but thank you for the feedback.
I don't know why it is so hard to get rid of Adobe's products that they they needed to provide the CC cleaner listed above.
