These programs run under all Western versions of Windows from Windows 98 to Windows 8 (they can also be run on Macs which can run Windows). All are completely virus-free (as attested by VirusTotal). The free trial versions can be made fully-functional by means of an activation key after purchase of a user license. The key can be sent immediately upon purchase (or can be obtained immediately after purchase), so there's no waiting required. For some programs you can purchase either a 3-month license, a 1-year license or a perpetual license (and site licenses are available for some). Updates to new versions are free.
