You can order ThumbsPlus right here on the Web.
Registered users can also purchase upgrades.
You can elect to receive your electronic distribution by FTP or using an Internet installation program. The registered and evaluation distributions are different. You cannot use your key to transform an evaluation copy into the registered version. We are in the process of automating the license key generation, so if you order the Electronic Distribution option, it may take until the next business day to receive your key via email. This key is required to install the registered version.
