receiving pop ups saying one of my Adobe apps is not genuine and will be removed which is not true

Hello I’ve been receiving pop ups saying one of my Adobe apps on my surface pro is not genuine and will be removed in 10 days. However all of the Adobe apps I have were purchased by my school correctly and I’ve had them for many years So it makes no sense to notify me now 4 years later and despite them being real

The company that the school purchased the software from may have sold it illegally.

or maybe it was legal, but each license was limited to a certain duration.

That may be the issue.  I remember a thread about some educational licences that were limited.

Or maybe, just maybe you have remnants of old unsupported versions of Acrobat and Flash Player that need to be removed for security reasons.  Use the Adobe Cleaner tool to wipe old apps off your system.

Restart your computer.

Hope that helps.
