If that doesn't work, you will have to extract the file to your system directory.
By default, this is C:\Windows\System (Windows 95/98/Me), C:\WINNT\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP, Vista, 7).
Make sure overwrite any existing files (but make a backup copy of the original file).
Reboot your computer.
If the problem still occurs, try the following:
1. Press Start and select Run.
2. Type CMD and press Enter (or if you use Windows ME, type COMMAND).
3. Type regsvr32 "filename".dll and press Enter.
If not works do this way:)
Dragon nice work, looking for interlude:P
