Hello
@Kam. I have this update issue with the PTR. My PTR version right now is 1.29.08803, and I tried updating it, to no avail. I tried to update it by going on battle.net in the program, and after a prompt to restart the program (it hits 100%), I am taken to the launcher, where I would click on either the repair or launch. Once it launches the program again, the version is retained. Sorry for the wall of text.
I tried to run the programs as Administrator,
edited the Warcraft III Public Test in the registry editor (I was uninstalling it),
reinstalling the program,
to no avail.
