I bought a new HP windows 11 PC a couple of weeks ago and with it came a free 1 month trial of Adobe Acrobat Standard DC. I installed the product from my Adobe account (version 22.003.20314) and immediately on use I got the same problems that had been reported in these forums "an error has occurred" and lockup etc. I am running the latest version of Wondows 11 (22H2.1194) with all avaiable updates installed.
I tried some of the range of fixes proposed by others, but no success and I don't feel confident about delving into the internals of my system. I have not gone through the unistall, Adobe clean and reinstall process as my machine and installation are brand new and should just work. I am forced to conclude that Adobe Acrobat is still not compatible with Windows 11.
