The virtual app-v package suddenly asks for a serial number precisely after 8 months. The package has not been modified.
Seems like this issue: Acrobat XI opens in trial mode or shows serial number screen even though you are a subscriber
Strange to note is that a local installation with the same serial number on a desktop seems to work ok...
The serial has been checked, and its OK.
Does someone know the right steps to take to get the software working again?
