Adobe Acrobat 2017 Citrix user EULA

I was recently tasked to install Adobe Acrobat 2017 on XenApp 7.1x. The serial number was provided and according to the vendor it is compatible with a multi-user environment such as RDS and Citrix XenApp/XenDesktop.

The install was not performed using any customized MSI to inject EULA or anything, just manually as an administrator accepting the default settings in the GUI.

However, users are now getting prompted to accept the EULA each time and it never sticks, even though I'm roaming their Adobe appdata.

I've tried setting the registry Software\Adobe\Adobe Acrobat\2017\AdobeViewer\EULAAcceptedForBrowser REG_DWORD=1, but that does not seem to work

Trying to get hold of a Adobe support appears to be impossible.

Anyone on the forum who can share how to rectify?

thanks
