How do I resolve an error of "R6030 - CRT not installed" during installation?

Make sure you're installing Ranger with Administrator permissions.

If this problem continues then this is most likely a result of corrupt MFC v7 Redistributables. To resolve this problem, unzip and copy the attached files into the system directory. Then reboot the computer.

As a safety measure it may be a good idea to make a backup copy of the original files.

System directory 32bit OS:

C:\Windows\system32\

System directory 64bit OS:

C:\Windows\SysWOW64\

Assuming the installation completed otherwise you may just need to register the Ranger.ocx file.
