·Go to the download page

Using the zip or rar file
1.Download diag.dll
2.Extract diag.dll from .zip. We recommend that you extract diag.dll to the installation directory of the program that is requesting diag.dll.
3.If that doesn't work, you will have to extract diag.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 diag.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 diag.dll and press Enter.
