How to replace msvcrt.dll

I was trying to replace msvcrt.dll with a newer version and everytime I try to copy and paste the newer version into my C:\windows\system\ directory, I get: "Cannot create or replace msvcrt: The specified file is being used by Windows." So how do I replace it?
 
I have this 3d modeling program called Milkshape3D, and I am using a plugin for it that imports and exports models for Battlefield1942. I was trying to import a model and as soon as I hit the import button I get the following message:


MS3D caused an invalid page fault in

I have been trying to find some info on how to fix this problem, and it seems that I need to get a newer version of msvcrt.dll. So, how do I replace it?
 
I have had this error before (can't remember which now) I just ended up ditching the program that gave this error. You could also try opening the program when not much else is running, it could be using too many resources.
 
It looks to me like 3310168954 is right (thats one hell of a name).

The msvcrt.dll file is either corrupt or old. It's used for running applications created in Visual C++. If this file is corrupt, then most if not all programs made in VC++ shouldn't run. If its old, then newer programs made in the latest versions of VC++ shouldn't run.

Replacing it with the most up-to-date version from the microsoft website should sort this.
 
Yeah, if he's using winXP then i would of thought that would have one of the latest versions anyway.

Just an idea: Have you tried Windows Update?

I was asking because the procedure for replacing files that are in use is different on Win9x and WinNT derived OS'es :)

You mean that solved your problem or that you tried but it didn't work?

If it didn't work try this:
open notepad
type:
[rename]
path-to-old-msvcrt.dll=path-to-new-msvcrt.dll
Click to expand...
So replace the last line with: c:\windows\system\msvcrt.dll=c:\temp\msvcrt.dll for example but make sure the paths match the location of each file on your PC.
Save the file as wininit.ini in your main windows folder (c:\windows most likely) and then reboot.
Windows should copy the new file over the older file before it starts loading everything else on startup.

(Edited to add: actually if you're using Win98, you could just press F5 right after the bios screen but before windows starts up and you'll boot into DOS and you could copy the files over that way easily as well)

Ok CareBear, I tried what you said and it worked, but there is still a problem. I copied over my orginal msvcrt.dll which was version 6.10.8637.0 with version 6.10.9359.0. When I then tried using the plugin, it still didn't work. So I decided to try an older version of msvcrt.dll, so I copied over 6.10.9359.0 with 5.00.7128. I then opened up Milkshape and opened up the plugin and imported a model and it Worked! BUT, some of my other programs that I then tried using didn't work, including Jasc Paint Shop Pro 7. It would say that msvcrt60.dll is linked to a file that is missing. So I am guessing that they were linked to a newer version of msvcrt.dll. So I think I know how to fix my problem. All I need is a version of msvcrt.dll that is old enough to support the plugin, but new enough to support Paint Shop Pro. Any ideas what version I shoud download?
 
Welcome to what's commonly referred to as "DLL hell" :)

You could try replacing the msvcrt.dll in your windows directory to the orignal one you had there and place the msvcrt.dll that works with the program in the same folder as the .exe and then running it. That might solve your problem.
