Let us know if you managed to get it working?

​@MarekMularczyk Curious, are you able to open Photoshop now? My first thought is your Photoshop has corrupted files. I would uninstall Acrobat. Run Adobe Cleaner Tool to cleaning up corrupt files, https://helpx.adobe.com/ca/creative-cloud/apps/troubleshoot/diagnostics-repair-tools/run-creative-cloud-cleaner-tool.html. Once that is done, delete the previous download that had Photoshop and empty your trash can or recycle bin. Then go back to Adobe Creative Cloud Desktop app, and download a ‘fresh’ and ‘new’ Photoshop for your computer.. 

What happens when you try to open Photoshop? Any error messages, pop up windows?
