Windows NT setup does not work due to missing or corrupted config.nt or autoexec.nt.

When you double-click any application setup program, nothing may happen. Also, trying to use the Add/Remove Programs tool in Control Panel or running the setup program from a command prompt doesn't work.

This can be caused by either:

Corrupted or missing config.nt or autoexec.nt
-or-
Corrupted or missing KnownDLLs
Many setup programs are 16-bit and depend on a working DOS Virtual machine NTVDM which depends on the dlls listed in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WOW
To fix a broken NTVDM, replace the dlls listed in the KnownDLLs list with versions from a working NT. These dlls are mosting in the system32 and system folders (but not all). Just find them on a working NT and copy them to the same location
