Every time I run Dishonored under Steam I get a pop up asking me for my Administrator password (I run as a normal user account, I imagine a UAC prompt would come up if I was running as Admin). I think this is due to the Steam first-time setup being run every time.

Is there any way to correct this issue?

Does any of your other steam games ask for the same? –  Jeff Mercado Nov 8 '12 at 2:38
    
@JeffMercado, nope, it is just Dishonored. –  James McMahon Nov 8 '12 at 3:54

To the person downvoting, could you please give a reason why so I can improve the question? –  James McMahon Nov 8 '12 at 3:54
    
have you moved the game somewhere else than the installed Steam folder? –  DrFish Nov 8 '12 at 10:20
    
can you clarify: is the account you run the game under in the administrators group? Normal UAC should not prompt for a password unless you are not an admin or you are accessing networked resources (or similar). –  horatio Nov 8 '12 at 15:21

You will need administrator rights to apply this fix

According to a Steam forums post:

You should launch regedit (runnable via Win + R) and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Valve\Steam\Apps\205100, right mouseclick on the right pane and click "new DWORD" (32-bit), name it "PhysXRedist" and give it a value of 1.

Restart the game and it shouldn't bug you anymore.


If you don't feel comfortable going into the registry yourself, run one of these commands instead depending on your version of Windows:

32-bit Windows:

reg add HKLM\SOFTWARE\Valve\Steam\Apps\205100 /v PhysXRedist /t REG_DWORD /d 1 /f

64-bit Windows:

reg add HKLM\SOFTWARE\Wow6432Node\Valve\Steam\Apps\205100 /v PhysXRedist /t REG_DWORD /d 1 /f

Do it from Admin account. Sorry to point out the obvious. But it helps people with similar questions. +1 BTW. –  ヴァイシャリ Nov 9 '12 at 16:01
    
UAC will always point you to the "Admin or else" dialog. –  DrFish Nov 9 '12 at 16:28
    
I concur as well. I thought WinXP not having such prompts, not having used it in a while. But WinXP does not have UAC. So I concur with your answer. :-) –  ヴァイシャリ Nov 9 '12 at 16:31
    
I can confirm that this works. Thanks. –  James McMahon Nov 10 '12 at 14:45
