Would anyone have an idea of this error message E_LIC_CERTIFICATE_SYNTAX on ADE 4.5.126523?
I'm using Windows 8 (on top of it extension to Windows 7).
I am first time user, neither myself or the computer has had any earlier versions.
Followed all instructions, created Adobe ID, and ADE installation seems otherwise complete,but when I am downloading any test books or free books, this is the message I get. No support source tried gave a hint on the issue or how to fix it.
Thanking you for any hints already in advance!
I have excactly the same issue. I have tried to de-authorize, uninstall, re-install and authorize again, with no luck.
My issue was solved by changing from Chrome to Edge(internet explorer should be the same), when downloading the original .acsm -file.
