           Summary: >wine-staging-9.3 patch causes Photoshop CS6 launch
                    error
           Product: Wine-staging
           Version: 9.6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

I've troubleshoot the issue not being able to launch Adobe Photoshop CS6 on
gentoo with differnt versions of wine >=app-emulation/wine-staging-9.4.1 up to
9.6. Other versions such as wine-proton-8.0.5c are also affected.
Photoshop CS6 is displaying a Messagebox containing "Error: 16"

The .wine prefix isn't relevant to run the Application. I've tried using a new
prefix as well.

It is possible to run it with wine-vanilla-9.0 to 9.7 and wine-staging-9.3 is
the latest version able to run it.
So it seems to be a patchset from >wine-staging-9.3 causing the issue.

Those 'CopyFileExW' and 'Read access denied' and 'Failed to resolve your host
name IP' messages appear in working versions like vanilla-9.0 too and are
irrelevant to the issue.

I'd be open to troubleshoot this with guidance without having to recompile wine
testing for every single patch.

Gentoo just released the wine-staging-9.7 package which is also working well.
So this might already have been solved in another related issue.
