I have a Dell Dimension running Windows XP Pro. The end of this past spring several programs suddenly wouldn't open due to an inability to locate a procedure entry point in the msvcrt.dll library. I tried reinstalling affected programs to no avail. I then found a site with instructions to fix this issue by reinstalling the original file from the XP reinstallation disc. I went through the recovery console and attempted to perform the following procedure:
cd system32
ren msvcrt.dll msvcrt.bak
D:
cd \i386
expand msvcrt.dl_ C:\windows\system32
exit

I ran into a problem at the "cd \i386" step. The file was unable to be found and now I am stuck with a computer that can't start Windows due to this missing file. If it comes down to it I can just reinstall windows, but I would prefer a solution that would be less time consuming than reinstalling all my software and updates. Thanks.
