I downloaded the .NET Framework. Then I downloaded the Sims2pack clean installer. When I try to go to it it says:::

"Application has generated an exeption that could not be handled
Process id=0x518 (1304), Thread id=0x980 (2432)
Click OK to terminate the application
Click Cancel to debug he application."

If I click OK, nothing happens
If I click Cancel it says:::

"Registered JIT debugger is not avalible. An attempt to launch a JIT debugger with the following command resulted in an error code of ox2 (2). Please check computer settings.
cordbg.exe !a 0xac
Click on retry to have the process wait while attaching debugger manually
Click Cancel to abort the JIT debug request"

Once again, no matter what I click...nothing happens.....

HELP!!

Maybe I'm doing something wrong...how do you open up the program???

If you double click a Sims2Pack, does it open with the Clean Installer or the Maxis Installer? This 'JIT' error is something that I've seen people encounter before, try these suggestions:
