Okay, whenever I open up certain programs, I get the error message:

[Program Name] – Entry Point Not Found

"The procedure entry point CsrNewThread could not be located in the dynamic library entry ntdll.dll."

My OS is Windows Vista 64-bit. I CAN’T run any registry cleaners, so do NOT suggest them.

I’m looking for more of a manual fix. Like downloading the ntdll.dll file and placing it where it needs to go for example in folders like:
System32
SysWOW64

I’ve already tried both of those, are there any other locations where ntdll.dll needs to be?

Other info will also be helpful, such as more information about CsrNewThread, I know nothing of its purpose or whether it has a location on my laptop.
