Is there a way to restore my Windows 2000 Professional?

My computer screen had an error message.
The dynamic link library VERSION.dll could not be found in the specific path C:\WINNT\system32;.;C:\WINNT\system:C:\WINNT\system32;C\Wbemjc\program files/

The Part that follows after the files/ is the different programs…quick time…firefox…epson…etc.
