Why I received "invalid license" error after I updated ezCheckPrinting and QB virtual printer
The ezCheckPrinting license codes are different for each version. For example: the old version 7 license will NOT work for the version 8. If you see license key issue, please follow the steps below:
Step 1: Find out the version number of your current ezCheckPrinting and virtual printer installed
Click the "Start" button , click on "Control Panel", click on "Programs", and then click on "Programs and Features". You will see the version number of both ezCheckPrinting and virtual printer.
Step 2: Find out which license you purchased
Please search your email account for the license message. You can search by "ezCheckPrinting" keyword.
For the version 8 and 9, you will see only one key for both ezCheckPrinting and QB virtual printer.
For the version 7, 6 or 5, you will see two keys: one for ezCheckPrinting and one for QB virtual printer.
