Rundll32.exe - Bad Image (error message)

ok i have tried and tried just searching for something to get this fixed but i cannot find anything that will work.
My computer crashed over a year ago and after doing system recovery i had problems with my sound. After some work my dad was able to get it working again, but not to long ago i got a wireless mouse/keyboard set, the keyboard works fine but I could not get the mouse to work and we discovered a virus on my computer and ran system recovery again but again sound does not work and mouse still does not work. My dad does not remember how he got the sound to work last time and I cannot find anything that will work. I don't know if the mouse has anything to do with it or not.
Any time I try to install the drivers for my Creative Sound Blaster Audigy SE sound card I get these error messages multiple times:
1. Rundll32.exe - Bad Image The application or DLL C:\windows\stystem32\streamci.dll is not a valid windows image. Please check this against your installation diskette.
2. Error loading streamci.dll %1 is not a valid win32 application
I have to press ok a lot of times to continue the unsuccessful installation.
I have tried free trials of registry fixers (can't buy one)
Also tried SFC /SCANNOW in run and it did not turn up anything.
Virus scan with norton shows no viruses right now

I have no idea what else to try

Where are you getting the drivers for you sound from. Do you have a cd or downloaded from the internet? What kind of computer is it, and HP, Dell, etc? Make and model. We'll try to narrow it down.

well thank you for replying to help but my sound card just installed with no problems a few minutes ago my guess is the SFC /SCANNOW scan fixed it after all. i am now about to see if i can get my mouse driver installed and if that wont work maybe you can help me out with that

Glad you got it fixed.
