The Max Function "EditWithPreview" returned with error -1: Internal error

Windows 8.1, Ableton Live 9.1.7, Max 7.0.1
Can't get Max 7 to open its editor from Live.
This may be an unusual case.
Just bought Ableton Live 9 suite after being a Max user for a long time. So, I have both Max 6.1.9 and 7.0.1 installed, but first time Live install, and Live newb. I did not install Max from the Ableton website....
Followed directions in the c74 video to change Preferences>Max Application to the Max 7 folder.
In a new Live Set Add a Max for Live Device, and try to open the Max device editor and get:
"The Max Function "EditWithPreview" returned with error -1: Internal error"
When I try Max 6.1.9 the Max 6.1.9 Editor opens
Anyone know how to fix?

This is usually down to the fact the Max is set to run as admin and Live isn't - therefore it can't launch the editor - check your setting for both programs and make sure they are the same....

Lee,
Exactly correct. Thank you.
