I got the same error. what I did was uninstall 3.65.0.500 remove registry keys for it.. then install 3.65.0.500 again and then 3.65.1 it worked flawlessly.

hi
i think the Number 3 in the application.xml is the update problem
I go to the ista p folder and delete the 3 in application.xml with editor. Looks (65.0.500)
Then i start the update and no problems. When update is finished i open again
application.xml with editor and write the number 3.
Looks (3.65.1.002)

Ista p is working
I hope i can help
