Download and Fix ISDone.dll Error

Installation instructions: 

Extract the .dll file from .zip file. We recommend that you extract the .dll to the installation directory of the program that is requesting the .dll.

If that doesn't work, you will have to extract the .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, win 8)
If you use a 64-bit version of Windows, you should also place the .dll in C:\Windows\SysWOW64\
Make sure to overwrite any existing files (but make a backup copy of the original file for safety).
Reboot your computer.
