This is the error I get when trying to launch Risen.
First time I even hear about a built-in parental control system in Windows...
Launching the game as an administrator or with compatibility mode does not help.
I checked the whole internet about disabling parental control but this functionality does not even appear in my Control Panel.
So I'm supposed to disable something that is not even installed on my computer.
Someone mentioned that same problem when trying to launch Risen on Microsoft forum (11 years ago) but no help from there either.
I'm running Windows 7 Ultimate, I'm the only user (hence administrator).

Then I tried Risen 2: "problem during installation" message when trying to launch the game.
Then I tried Risen 3: same...

Any idea?

Thanks for your help Gydion!

I was not able to test the external link ( h t t p : //ubeogesh-things.blogspot.com/2012/08/resolve-it-finally-game-explorer-aka.html) provided on the topic you mentioned here (blocked in China) but at least I was able to efficiently search for a solution.

Tried this software: h t t p : //www.mediafire.com/file/2mrtxy4eo4pmi2g/Stop_Game_Explorer_1_1.zip/file mentioned in this topic h t t p s : //www.gog.com/forum/general/games_explorer_gameuxdll_and_rundll32_issues_with_offline_gaming/page1 --> didn't work.
Tried the command: regsvr32 -u c:\windows\SysWOW64\gameux.dll --> didn't work.

Found this topic: h t t p s : //answers.microsoft.com/en-us/windows/forum/windows_other-gaming/windows-7-game-explorer-interfering-with-game /efd39c74-cfab-4c2c-b6c5-834b8849a1b3?page=2

Copy pasted:
if %PROCESSOR_ARCHITECTURE% == AMD64 (
set filename=%windir%\SysWOW64\gameux.dll
) else (
set filename=%windir%\System32\gameux.dll
)

TAKEOWN /F %filename%
ICACLS %filename% /grant %USERNAME%:F
ren %filename% "gameux.dll - go to helll!!!"
pause

in a text file, changed extension to .bat, executed, problem solved.

Now I suppose if problem happens on other games because of this fix I'll just have to create a reverting script like:
if %PROCESSOR_ARCHITECTURE% == AMD64 (
set filename="%windir%\SysWOW64\gameux.dll - go to helll!!!"
) else (
set filename="%windir%\System32\gameux.dll - go to helll!!!"
)

ren %filename% gameux.dll
pause

Anyway, I've been able to launch the game and I can enable/disable this fix with just one double click.
I can also launch Risen 2 now, but not Risen 3 :( do you have an idea?
Why is this bug not mentioned in the official support page (because I suppose it will happen 100% of the time for every user still running Windows 7) and/or can Gog provide a similar script automatically executed before launching the game?

Thanks a lot Gydion!
