All Treskat apps require a serial number also known as a license. Older verions required a White License Management floppy disk. We no longer sell these older floppy disk versions.

If you have an older White License Management Disk then click on LicenseMgr found in the C:\Treskat folder. The rest of this page is for the newer single computer versions.

New Treskat apps are for use on a single computer. An internet connection is required (for license compliance) whenever you run the app. If you want to switch computers there is a $50 fee for one ($100 max for two or more) to cancel your old serial number and issue a new one.

All apps purchased today get free annual updates for life!
