Currently using the Sheridan widget for the OLE design, which is incompatible with/does not support Windows 10 (64 bit).
Problem occurs while opening the OLE widget in Gen Toolset for view/modification from the development machine.
Please share a list of OLE designers that Gen supports and has certified as 64-bit compatible, or any other guidance would be greatly appreciated.
Per the Gen 8.6 Technical Requirements General Comments page, the "Active Control Support Policy" shows that the only OLE/ActiveX control supported is the FarPoint Tab Pro control:

Active Control Support Policy
Support of TAB controls for GUI applications is limited to the Tab Pro control provided by FarPoint Technologies Inc. While this control is no longer supported by its distributing company, it continues to work with this version of Gen.
Remember that Gen has not been tested with all ActiveX controls available in the market. Therefore, we cannot guarantee they will all work with Gen.

From our research, it appears that the old Sheridan Data Widgets are now called Infragistics Data Widgets but still date back around 20 years: Component Source > Data Widgets
They have not been tested with the Gen 8.6 Toolset (it is not known if testing was done with any specific older versions of the Gen Toolset).
The feedback from Gen Engineering confirms that per the "Active Control Support Policy" above, only the FarPoint Tab Pro control is supported with Gen 8.6.
For further details the current FarPoint owner GrapeCity can be contacted ([email protected]). This KB article also covers it: Gen and FarPoint TabPro OCX Installation
If that control does not help, and another is found that satisfies requirements then the onus would be on the user to test it with Gen 8.6 Toolset.
Any official support for such a control would require an enhancement request i.e. a new idea via the Broadcom Ideas Community
