Extract atl100.dll from atl100.zip. We recommend that you extract atl100.dll to the installation directory of the program that is requesting atl100.dll.
If that doesn't work, you will have to extract atl100.dll to your system directory. By default, this is:
- C:\Windows\System (Windows 95/98/Me)
- C:\WINNT\System32 (Windows NT/2000)
- C:\Windows\System32 (Windows XP, Vista, 7)
If you use a 64-bit version of Windows, you should also place atl100.dll in
Make sure overwrite any existing files (but make a backup copy of the original file).
Reboot your computer.
