Hi asifs737004,
How many users are connected to a server?
What is the version of Adobe Acrobat? And how many seats you have purchased with a serial number of Acrobat Pro? Was it a volume license serial number?
Message you are getting: “Activation limit reached” or “Sign-in failed” error
Is primarily linked with an individual serial number. Let me know if that helps.
Regards,
Tariq Dar.
