I would suggest looking to see if there is a patch available for that game. In a way, you are lucky that you can manually kill the process, because I have run into a couple that couldn't be killed short of a reboot.

This needs bumping, or needs more attention atleast.
Same problem and all.

Older games will end up giving rundll32.exe an entire 25% of my cpu (4core) when I double click the exe (Older games including max payne 2, ut2004, silent hill 2 and even quake 1 etc and many more...)...thats all that happens, you can watch this in Task manager...but the game doesnt start, you double click the .exe again THEN the game starts, 25% on the 32bit game 25% on rundll32, awesome thing is you can just end rundll32 and the game runs absolutely fine regardless...
(I have a theory that its AVG on access scanning or something doing this)

But awkwardly enough.
Modern games such as Bioshock, Fallout, Crysis: warhead and Empire total war, all stick to respective 32/64 capability, with no fuss with rundll32.exe

Strange...
Not like DirectX could have any qualms with rundll ?
Maybe even the gpu drivers ?


Although I cant remember when this problem started, I might be able to say it was recent (And within that time I have not really done anything too significant to cause this), but I can definitely say I never had this problem a few weeks back...

rundll32 fix

Hello everyone,

I spent countless hours trying to figure out how to fix the issue with rundll popping up after starting a game but the game wouldn't start and would eat up resources. I finally found something that worked twice, so I thought it may be worth mentioning. I don't know why or how, but for some reason, when you install a program called "Rundll Errors Fix Wizard" (can be found at the following link: Rundll Errors Fix Wizard - Free software downloads and software reviews - CNET Download.com), it rids your computer of the problem. The funny thing is you don't even have to run the program; you just install it, and the problem goes away. I still see no logical conclusion to this, but it worked for me, so maybe it will work for you too. Cheers!

Oh god, it worked.

Dunno what the real issue is beyond this, but the cnet app worked.

I have run the "Rundll fix wizard" from CNET and I am still being killed by "runaway" rundll32 processes. I am not even running games, just some Java IDE stuff, and mind mapping piece of software. I have cleaned my reg, I have scanned for mal-ware. I still have to re-boot every 30 mins or so. This must be because the 32bit software does not play nice with the 64bit architecture... This issue really needs to be escalated. This is a major issue with windows 7.

Well I have a fix for the RUNDLL32.exe issue. Don't run explorer 32bit on your 64bit machine. Use Firefox, or some other browser. If you do run explorer on your machine kill the rundll32.exe process (both of them because they always seem to spawn 2). Some of you might be asking why are you 32bit explorer...try running youtube on 64bit or running BBC's radio player on 64bit and see what happens.

Solution

I had the same problem for 6 months finally i found a method by which all my 32 bit games started working flawlessly....
Step 1: Open Games Explorer
Step 2: Click on Option in top bar
Step 3: Check "Never cheeck online" Option
Step 4: Uncheck "Download art & information" & also uncheck "collect most recently played game info"
Step 5: Click OK & close Games explorer
Step 6: Right click on the exe file of the game & go to properties & in compatibility mode select windows xp sp2 & check option disable desktop composure & disable visual themes & check run as administrator
Step 7: In same menu go to Security tab & in groups or user names panel select Administrators & click OK
Step 8: Run the file
Step 9: Sit back & enjoy....

Note: for some games, some files like launcher.exe etc also had to be set the same way as for the main exe file from which the game starts.

If it works do comment...

the following worked for me:
1) Run services.msc
2) Stop and disable BITS (Background intelligent transfer service)

Just disabling options from games explorer didn't help (maybe its because i run built-in administrator account?)

Hi there
I had the same problem but I found the location of rundll32.exe by task manager &
deleted it by tuneup 2011 shredder.Now I have problems with many of my software &
I can't run the old game(Scarface:The World Is Yours).
The problems started here,when I wanted to run the game,
Rundll32.exe appeared with over 60% cpu usage & I did a huge mistake by thinking that must be a malware....& deleting it.
I can't restore my windows though,because I turned it off & I don't have a restore point.
So what can I do to restore the Runddll32.exe(it is strange that when I search,there are various Rundll32 s & there is one in system32)
plz help solving my problem,thanks.
