i had this happen on 13/6/18.
i tried several times the instructions on the link you advised and could only get to step 3.
i click ok but there is no window popping up for step 4. (and i also checked behind all other windows.)
Did you again try selecting 2144 Game Centre from Control Panel?
yes, from control panel.
Unfortunately, I am unable to reproduce the scenario at my end. Once you click on uninstall from Control Panel, could you mention the detailed steps you followed. Did you try restarting your machine once and then following the steps?
Please see comment #43 at Re: Adobe update on 6/12/18 include 2144 game center 22.214.171.124 and see if that solution works for you.
The step to go to AppData-Roaming-2144 is the C:\Users\<YourUseID>\AppData\Roaming\2144 directory. AppData is a hidden directory, if it's not visible, just manually enter it in the address field.
This issue has been fixed and should not happen in future updates.
I FINALLY uninstalled the 2144 game centre.
i had to restart my computor several times, each time trying to uninstall until it worked.
Instructions for removing 2144 Game Center are posted at Uninstall 2144 Game Center
what a complete waste of time
thanks everyone for your help.
