ComponentOne Studio ActiveX, a widely used collection of UI components for legacy desktop applications, is reaching the end of its support cycle. After two decades of supporting this platform, MESCIUS (formerly GrapeCity) has decided to discontinue full support for its ActiveX products.
MESCIUS adheres to Microsoft's "It Just Works" compatibility guidelines for its ActiveX controls on Microsoft Windows 7, 8.1, and 10, as well as Windows Server 2008, 2012, 2016, and 2019. However, due to changes in Windows operating systems and Microsoft's end-of-support policies, MESCIUS is no longer able to provide maintenance updates for any of its ActiveX controls.
ComponentOne Studio ActiveX Edition's full support will cease on December 31, 2023. The C1ControlPanel application will continue to offer the final version of the ActiveX Edition for download and licensing.
Starting January 1, 2024, licenses will still be available for purchase, but only licensing support will be provided. The MESCIUS ActiveX forum will remain active indefinitely, and the knowledge base will continue to be enriched with existing solutions.
