Unfortunately the EQ6 installer is not compatible with Windows 10. EQ6 was originally designed for Windows XP and updates to the Windows Installer’s security policy in Windows 10 prevent it from being installed.

If you have EQ6, and cannot install on Windows 10, an option would be to upgrade to EQ8 at our upgrade discount:

Upgrade from EQ6 to EQ8

Note: You do not need any prior versions installed before installing the Upgrade to EQ8.
