Download an older version of BiblioMaker, if for any reason you don't want or cannot use the current version.
Only the last version of each generation is available.
Click on the software you want to download. You get a setup program you just have to start up.
⚠️ CAUTION: installing a version higher than your current version will irreversibly update your data file. Do not install a higher generation than your current version if you do not have an update subscription because a new activation key will be required.
