Downloading it now - only getting XP and Vista.

Maybe when you built it, John but the version I have (that came preloaded with WB7) has a Win7 sub

2of3 is correct. The skin which comes with WB subscription has a W7 substyle.

GregII, when you say "downloading it now" where are you downloading from? And how?

The only Aero Midnight I see is here: https://www.wincustomize.com/explore/windowblinds/6780/

and it states:

"Aero Midnight is available free to subscribers of Object Desktop. It can be downloaded via Theme Manager, which is included with your Object Desktop subscription."

I wonder if there is more than one version of the skin, and whether you're downloading an earlier version? 

Try downloading it with Theme manager, or if you have Theme Manager installed, try to see if it has a 7 substyle if you apply it through there.

You might have to delete the skin, and if you have Theme Manager installed, uninstalling it and then re-installing after deleting the skin in WB config to see if you can get the W7 substyle that way. That's if you have an active ODNT subscription. Otherwise, don't do it without backing up the Aero Midnight version you do have.. 

Well, if it doesn't have the 3 versions, then give my thought a try.

Greg, do you have theme manager installed and is your ODNT subscription current?

If you don't have TM installed, don't install it yet. Back up your newly downloaded version somewhere else and rename it xyz.wba. don't install it. Uninstall the version you currently have in Windowblinds config.

Then, just install TM and see if you got Aero Midnight with it. If you did, take a look at it in WB config. See if it has 3 versions. If not, just rename and install the one you downloaded.

Glad to be of help.
