·Go to the download page

Using the zip or rar file
1.Download wmdvi.dll
2.Extract wmdvi.dll from .zip. We recommend that you extract wmdvi.dll to the installation directory of the program that is requesting wmdvi.dll.
3.If that doesn't work, you will have to extract wmdvi.dll to your system directory. By default, this is:
C:\Windows\System32 (Windows XP, Vista, 7, 8)
C:\WINNT\System32 (Windows NT/2000)
C:\Windows\System (Windows 95/98/Me)
4.If you use a 64-bit version of Windows, you should also place wmdvi.dll in C:\Windows\SysWOW64\
5.Make sure overwrite any existing files (but make a backup copy of the original file).
6.Reboot your computer.
7.If the problem still occurs, try the following:
8.Open Windows Start menu and select "Run...".
9.Type CMD and press Enter (or if you use Windows ME, type COMMAND)).
10.Type regsvr32 wmdvi.dll and press Enter.
