Hi David. First off, blame the people that wrote the installer, there is no excuse for this not working correctly, especially on NT. you could try to manually do what the installer does for updating system files. In the registry there is a key called HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce. To open the registry, Start->Run->"Regedit". If you create a new string value under this key, call it what ever amuses you, and place the command: C:\WINNT\System32\xcopy.exe C:\msvcrt.dll C:\WINNT\System32\msvcrt.dll /Y as its value. (replace C:\msvcrt.dll with the source file name) Then when you reboot the machine it will execute the commands in the run once key before the system gets running enough to be locking system files. It will automatically remove the key. Good luck.
