I tried to install lightroom 6 from my account page at Adobe. It dowmloads the program but when I try to run it I get the error "installer failed to initalize. Download Adobe Support Manager". There is no such program any longer. How can I get this program to install again?
Mac or Windows, and exact version of your operating system?
Is that the serial number version, or part of cloud subscription?
If cloud subscription,
Are you using Cloud Manager to install all programs https://www.adobe.com/ie/creativecloud/desktop-app.html
Two ideas that MAY work to install and/or run old programs in Windows 10
-RIGHT click the program icon or EXE and select a compatibility mode in the pop up option window
-and/or select Run as Administrator to assign FULL Windows permissions
