The license code is not valid for this release

Return to Introduction  Previous page  Next page


The license code you entered is for an older release of TN3270 Plus. The license code is generated for a specific release and will not function with newer releases of TN3270 Plus.

The product release level is three digits separated by periods, for example, 3.4.0. The license code only checks the first two digits, so a license code created for 3.4.0 will work with releases 3.4.0 through 3.4.9. In addition, license codes for release 3.3 and above will work with the next higher release. For example, a release 3.4 license code will also work with release 3.5 (3.5.0 - 3.5.9). However, if you try to use a release 3.4 license code with release 3.6.0 or higher you will get the above error message.
