every time i close skyrim i get this error. "runtime error 216 at 03f74bfa", tried to google it but nothing in there. there were literally no results!! IN GOOGLE!

so.. yeah, what is this?

Microsoft states it's a trojan virus. http://support.microsoft.com/kb/259279

But generally it's probably not the case. the 03f74bfa is a memory adress. It might be a faulty RAM, although i wouldn't concern myself much with it if your pc runs normally.

i have experienced some slowing on my pc lately and skyrim DOES works slowly a lot of times.. what do i do?!

Well, download an antivirus first. I'm not sure which ones are good or not, but i assume you can find one decent one without much trouble. Scan your system and remove all viruses and spyware/malware. Then try to run the game again. If that doesn't help it's most likely a faulty memory.

if its faulty memory what then?

Well, the easiest way to settle the problem is to simply unplug one RAM brick per time and see which one is causing the problems. Then, just toss it away and get a new one. When RAM dies it's dead, it can't be fixed.

Edit: Mind you it could be any amount of problems, it could even be System related. I would scan the computer first for viruses, then if the memory is not at fault try to find another cause of problems, most likely the operating system.

Edit: Memory faults usually give out a Blue screen of death problem, so it doesn't have to be it. It could be just the system being buggy (long time since last Windows reinstall?)

Replace it with new memory, what else?

well i WAS planning to buy 8gb ram.. reinstall windows? seriously? why

Get Memtest86 at http://www.memtest.org/ let it run a few hours and see if it spits out any errors. If it does replace your ram, if it doesn't something has gone wrong with your windows installation.

Runtime code 216 is a conflict between 32 and 64 bit binaries:

--------- ERROR_EXE_MACHINE_TYPE_MISMATCH 216 (0xD8)
The version of %1 is not compatible with the version you're running. Check your computer's system information to see whether you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.

---------

Now, what the exact cause of this is... impossible to say, but there is nothing wrong with your memory. Does the dialog box have a title? Skyrim? Steam? Something else?

nope title is error, it counts as a skyrim window tho according to the taskbar

still happens after i cleaned my pc from viruses. when i close skyrim i also get an error saying skyrim has stopped working X_X
