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.

I have had to reboot my computer several times due to using limewire and downloading games. I’ve never had a problem when I downloaded songs, but since rebooting, there’s this annoying error message that keeps popping up stating to use a registry cleaner because my registry is corrupted or damaged. I have downloaded several registry cleaners (freeware) and I assumed that the problems were fixed, but I keep getting this error message–even after I cleaned the registry about 5 times, and each popup message uses a different download location, i.e. registrycleanerxp.com, and www.cleanregistry.com. How can I fix this problem?

I have been using Microsoft Office 2007 Professional Plus for nearly a year now. I’ve always been able to run every aspect of Office without fail. I haven’t changed any hardware or significant software changes in that time, but within the last few days, it has quit working. Whenever I try to start Word, Excel, PowerPoint, Access, or Outlook, I get an error message saying that there isn’t enough memory or disk space to run those programs. I can run every other program on my computer without problem. I have twice ran the Microsoft Office Diagnostic tool, and it says there is no problem with my system. My anti-virus, anti-spam, and anti-malware tools can’t find anything. If I contact Microsoft about the problem, their free troubleshooting help doesn’t apply to me. They want to charge me just to CHAT with someone who may or may not be able to help me. I don’t know what to do to fix this, but I don’t want to pay them money. Please, can anyone offer any suggestions?
Canadian Bacon’s answer fails. The processes that are currently running on my PC aren’t taking enough memory to cause a problem.

I keep getting DLL error message when I start up and messages keep popping up telling this program has stopped working and that program has stopped working; including internet explorer and Firefox. Would this step fix it?

I usually use Netscape but my son went to Internet Explorer and an error message popped up and now I have this winfixer junk on my computer. Norton removes it or says it does but if Internet Explorer is opened then this comes right back. I can use Netscape no problems but not Internet Explorer. Is it possible to get this off? It was never downloaded just popped up and won’t leave.
I understand. The netscape version I am using has both foxfire and internet explorer on it. I use the foxfire option. However some sites will not respond with netscape and end up having to use IE. The first person that responded. Forgive me but how do I know your site is also safe when this winfixer keeps trying to get me to download things too. Can you calm my fears?
