It depends; If the license file and software version match (for example, v9 licensed file will work with v9.5 Veeam software), then the license will work. If they do not match, the file will not allow installation. For example, if you try to apply a v8 license to a v9 installation, you will receive a “License expired” error message.
You can always download a license file for current, as well as the most recent previous version of our products from the license management portal.
To confirm the license file version please open using any text editor application.
