I also get an error message upon install: sims3

[mortimusprime]

I mount the image, start the install, then repeatedly i see:
\Game\Bin\bin\cs-CZ\Sims3Launcher.resources.dll
Error: Incorrect Function

it will get pretty far into the progress bar with this error popping up every couple minutes, and i click retry.
somewhere near the end of installation it just refuses to go any further. then it starts back up at:

Electronic Arts\The Sims 3\caches\Sunset Valley.objectCache

any help would be greatly appreciated.

okay, from what i can tell, the download sounds corrupted, well thats if you say that you have installed everything in the correct order, you know i have my step by step guide on here, did you follow that exactly if not, then theres a chance you may have corrupted it yourself.
big problem about that is..download again.
i know its a pain in the backside but there isnt much you can do, because your getting the error with the sims launcher, thats basically the "glue that holds the game together" so to speak.
so tell me this, was you following my guide..did you use any third party cracks not mentioned in the guide or readme file...
