Macrovision has announced the end of support for several older versions of InstallShield, effective November 1, 2005. Included in the list is InstallShield Express versions 2.0-3.x. Support will continue for InstallShield Express 5.0 and later. See the Macrovision End-of-Life Policy for the official announcement.
The InstallShield Express Limited Edition for Visual FoxPro that ships with VFP 9.0 is based on InstallShield Express version 5.0 and should therefore still be supported. The InstallShield Express Limited Edition for Visual FoxPro that ships with VFP 8.0 is based on InstallShield Express version 3.54, for which support is apparently ending.
The current version of InstallShield Express is version X (as in 'ten'). The InstallShield Premier and Professional editions are already at version 11. In an InstallShield webinar yesterday, InstallShield Product Manager Bob Corrigan announced that Macrovision will be releasing version 11 of the Express product in "mid-2005".
