The solution posted here in 2009 by Somu still helped me in 2011. I typed rundll.exe "application not found" in Google because I was about to reformat my computer and reinstall Windows.

OPERATING SYSTEM: Windows XP Professional SP3

EVENT:

1. Got a typical Spyware add in my task bar displaying Windows Antivirus found X amount of viruses and spywares on your computer, with Windows Security Center icon
2. Did a complete system scan with my NOD32 Antivirus, which by the way is the first time to allow a malware on my computer in over 4 years. Around 16 bad files found
3. Rebooted
4. Tried to open almost any program in Windows and got a pop-up with Choose program to open file...and also other error messages such as rundll.exe Application not found. Only way to have a program work would be to right click and select Run as..., but even then many programs wouldn't fire up and end up with an error message
5. Rebooted to reinstall Windows
6. Realised I had no license key
7. Rebooted to go get a license key extractor
8. Downloaded 3 license key extractors
9. All key extractors would result in no key found
10. Typed rundll.exe "application not found" in Google
11. Found that post at top
12. Applied Somu's solution
13. Problem solved

Thanks Somu for saving me 2 hours!

The same problem appeared on my computer last week, and I was just about ready to throw my laptop away (in my defence, I am an IT idiot, and my laptop is about 5 years old)... Just tried the solution posted by somu, and it works! Which, really, is just about the most exciting thing that has ever happened to me online. So, I registered to say thank you so much for your help (even if you did give it about 2 years ago), I can't believe I've got a working computer again, and it didn't cost me a thing.

I registered on here just to pass along that I had a problem with my Gateway Netbook having this issue (I suspect someone using it had downloaded "antimalware doctor" and caused the issue) and somu gave the solution that worked a miracle!!!!

My thanks to somu and for this forum for this solution.

Hmm, precisely the same problem as the OP's, however, when I try Somu's suggestion, but when I click "yes" I get an error that says it's not a registry script and can't import it to the registry because it isn't binary. I saved it via "all files" as instructed...

Yep, as I pointed out "I saved it via "all files" as instructed".

After a little googling, I found I wasn't the only one having this problem and found a guy in another forum that posted a successful file for others to download; it worked:
