Error 1923 for Acrobat DC install under Windows 7
The Acrobat DC installer fails (somewhere after 80% progress) with Error 1923, even if I run it as Administrator (right-click on the installer exe).
This started as an upgrade from Acrobat XI, which the installer removed on the first round; control panel now shows no Acrobat version installed. (I do have Flash and Creative Suite 6.) Fails with the same error, whether run as user or admin.
"Error 1923: Service Adobe Acrobat Update Service (AdobeARMService) could not be installed. Verify that you have sufficient privileges to install system services."
What next?
Windows 7 Professional, SP 1, 64-bit.
Acrobat DC downloaded from Adobe today.
