"Unable to elevate to admin rights" error, when admin user

[amberwiser]

I am trying to download Adobe Digital Editions and I keep receiving the error message

Unable to elevate to administrative rights, error 786

I am the admin! I have turned off the password, I have right clicked on the program and chosen 'run as admin'-then nothing happens.
Any help would be appreciated

Try this:

SOLUTION: download the setup.exe for ADE, not using the flash install version.

Before you run it, right click on it and check "run as administrator" under the compatability tab. Also under the general tab I clicked on "unblock," which might have made a difference.
