Ok, I need some major help. Here is what I did to screw up my computer. I was tryingto install some software and upon installation, I was getting an error. I looked up the error and it was related to an outdated version of the Shell32.dll file I was using. I am currently running Windows NT 4.0 SP6. Well, I tried to copy a newer version of the Shell32.dll file to the system and now it is saying its corrupt and it will NOT boot. Here's more bad news. I don't have the Windows NT Install CD. I do have the 3 Setup floppies as well as the ERD. However, none of that seems to work. I have valuable data on the drive that I cannot lose. Please someone help!

Here is the error message that I am receiving in case it helps.

STOP c0000221 {Bad Image Cheksum} The image Shell32.dll is possibly corrupt

High Encryption or Standard Encryption, get the bigger Network Download as you need to run WinZip or similar on the entire package. Other offerings at this site are for online installations and won't work for file extraction.

WinZip will extract shell32.dll from inside either self-extracting exe like Service Pack 6 or the above cab file.

See this site for info on deciding if you have or have not the Desktop Update.
