            Bug ID: 49068
           Summary: 'Access violation in riched20.dll' with certain
                    GOG.com installers
           Product: Wine
           Version: 5.7
          Hardware: x86
               URL: https://www.gog.com/game/teenagent

          Severity: normal
          Priority: P2

      Distribution: ---

Some (but not all) of the game installers from GOG.com are plagued by this
problem.
After the language selecting dialogue the following error messages are shown:

"Access violation at address 7AC51DD3 in module riched20.dll."

Followed by

"System error. Code: 1400. Invalid window handle."

Afterwards the installer quits prematurely.

Reverting commit 650aebadb7ade8b95766b5f2a9062c2210b0eca1 fixes the problem.
'winetricks riched20' also acts as a workaround.

Plain terminal output doesn't show anything unusual.
Looks like the problem occurs when Wine is compiled using the "--without-mingw"
flag.

The game 'Teenagent' is available for free on GOG. If you have an account then
you can reproduce the problem with that (download size ~20 MB). Otherwise just
let me know what debug log would be helpful.
