Opening a .pdx-file after upgrading to 2022 version triggers a repair installation. Eventviewer lists "%programfiles(x86)%\Adobe\Acrobat Reader DC\Reader\AcroCEF\libGLESv2.dll" as missing (and it is). The repair installation cannot fix this. After repair ran a acrocef_1 or acrocef_2 folder exists containing the file, but the next run will still trigger a repair. Reboot or removing the acrocef_x folder does not solve this.
