The uninstaller doesn't work

I’m trying to uninstall a trial version of eM Client, but finding that I do not have the sufficient access to the uninstaller. (I’m the admin user.) I also cannot find an uninstall.exe or similar in the program files when I look for them manually.

“Windows cannot access the specified device, path, or file. You may not have the appropriate permission to access the item,” it says.

I reinstalled the program to see if I could then uninstall it but no luck. 

I wound up using a 3rd party uninstaller to get rid of it, just so you know there’s a problem in there.
