windows 11 (edition: workstation) no longer boots after master suite cs6 installation

hi everyone,

 

i got the following problem and i'm looking for a solution without deleting all adobe registry entries. can anyone help?

 

after the master suite cs6 installation on my windows 11 (edition: workstation), the pc no longer starts.

 

procedure:


the security setting core isolation was deactivated so that all master suite cs6 drivers could be installed without problems during the setup and no errors occurred (otherwise i got the following error messages: PxHlpa64.sys driver and Px Engine Device Driver / Rovi Corporation could not be loaded). after the installation all master suite cs6 updates were applied with the application manager. the core isolation was reactivated and windows 11 (edition: workstation) was rebooted.

 

note:

 

there was not such an error on my windows 11 (edition: pro)

 

many thanks in advance!

RS

Correct answer kglad

current trial:

- run windows 11 setup

- format hard disk partition
- install windows 11 workstation
- install all windows 11 updates up to version 24h2
- install master collection cs6 (current version from my Adobe account / products)
- right mouse click on MasterCollection_CS6_LS4.exe
* properties -> run program in compatibility mode for -> windows 7
* run as administrator
- error message during installation:
* a driver cannot be loaded on your system -> Driver PxHlpa64.sys
* a driver cannot be loaded on your system -> Px Engine Device Driver for 64-bit Windows Rovi Corporation
- reboot
- notification: automatic repair is being prepared
- selection menu with the message: automatic repair could not repair your PC
* shut down
* advanced options


hopefully not in that order, but for that driver error:

CS6 is 13-year-old unsupported software that was never certified to run on Win11 machines.  You're taking a big risk with incompatible old products on new devices. Personally, I see no upside in it.  Even if it does install, there's no guarantee it will work as expected. 

 

Best advice is to replace old products with supported ones.

if that fails, do you have any data that's essential?

 

if not, reformat your hard and then install your os and rebuild your software.
