I asked my URC rep last week or maybe it was the week before and he said he was told that the DMS-AV, when set to bypass should pass 4K content. If it does not, I will be pretty pissed that URC led me down that path. I purchased some 4K HDBT pairs for the two DMS-AVs we have in our system with JAP 3G gear.
I suggest not mixing the two. It is fine to use the URC for the interface and Dash for the background programming, but don't use both for back ground programming. Also, I would put Dash Lutron first in the tree. And have separate log in and passwords for each.
You should have some similar options that will help you get it to run as Admin always. It doesn't matter if you only have one user, its a different level of clearance within the OS. My Win7 32 bit has the same options, XP should be very similar I would think.
Can you hit me up on HipChat? I can provide more immediate support that way.
The license gets immediately added to your account. Thank you for your purchase by the way. But now all you have to do is activate the license from the Dash Apps Page of the site you want to use it on.
The best way to show the commands is with using screen shots.
