DHD Software might not run correctly under Windows 7 right away. This may particularly apply to software like Toolbox4/Toolbox 4.5.

In order to be able to use the software anyway, it is necessary to change the compatibility settlings for the program.

Right-click the program icon, hit Properties, and then click on the Compatibility tab. Activate “Run this program in compatibility mode for:“. Select “Windows XP (Service Pack 3)“. Activate “Run as administrator” and confirm with OK.

The program should run properly now.

If the above steps are not successful, you might, under certain conditions, be able to run the program in “Windows XP” mode. This mode is a Microsoft option which needs to be additionally installed for the Windows 7 Professional and Windows 7 Ultimate versions.
