This forum is for all questions, technical or not. Sometimes we might direct you to the proper source, if necessary, such as with the vailidity of your license files.
I will check with our documentation team, but once you purchase a license and install/assign it to a machine, that license does not expire. If you install BESR without a license, it will show up as unlicensed in the COMPUTER STATUS and on the report I mentioned prevously, and will show when that installation temp license expires if it has not been <60 days since the install.
