Solution 1Recommended

Restart the FLEXnet Licensing Service

The FLEXnet Licensing Service manages Adobe's software licenses. Manually restarting it often resolves the 148:3 error without requiring a software reinstall.

Adobe Acrobat relies on the FLEXnet Licensing Service to verify your product activation. If this Windows service is stopped or set to disabled, Acrobat will trigger a licensing failure upon startup.

1
Open Windows Services

Press the Windows Key + R to open the Run dialog box. Type 'services.msc' into the text box and press Enter.

2
Locate the Licensing Service

Scroll through the list of services until you find 'FLEXnet Licensing Service'. Right-click on it and select 'Properties'.

3
Change Startup Type

In the Properties window, find the 'Startup type' dropdown menu and change it to 'Manual'.

4
Start the Service

Under the 'Service status' section, click the 'Start' button. Once the service is running, click 'Apply' and then 'OK'. Relaunch Adobe Acrobat to see if the error is resolved.

Service Restarted: If Acrobat opens successfully, the licensing service was the root cause. You will not need to reinstall the software.
