Failed to run Photoshop cc 2018 [in Windows 11 Beta]

1. It's easy, just disconnect the internet, photoshop CC 2018 will install just fine on windows 11.

It is absolutely possible to install 2018 under Windows 11.

1) You have to install Photoshop 2021 completely. (Regestries need to be written to trick 2018 in a genuine repair)

2) Replace the Photoshop 2018 installer "Set-up.exe" with the Photoshop 2021 "Set-up.exe".

3) Run the Photoshop 2018 installer (Which is now replaced by the 2021 installer).

4) The installer will fail to gather any data, paths or even show you a dialog and will automatically install Photoshop 2018 on your C: Drive assuming that it's Windows 10, even if it isn't. I haven't found a way around it, but this is atm. the way to go.

The 2018 Version does not know about Windows 11 and just straight out refuses to install, even if it runs perfectly fine under Windows 11.

Proof:

"Microsoft says the official release of Windows 11 (what the company calls General Availability, or GA) will arrive on new hardware in late 2021. Most knowledgeable observers expect the Windows 11 GA release to arrive in October 2021, and you would be foolish to bet against them."

So, some time after then. 3-4 months.

Thanks for letting us know about this problem on a beta system, though of course no "fix" can be expected. I assume you've reported it to Microsoft, and you're still able to use Photoshop on your live machine.  Of course if a fix is needed, Adobe will do one soon after (MAYBE even before) Windows 11 is released, but it will only affect the latest Photoshop.
