VS2022 MFC dialog editor cannot edit dialog hosting ActiveX control

Question

I am using VS2022 17.6.5, working on a MFC C++ application. I am trying to visually edit a dialog box which has the ActiveX control "Microsoft DataGrid Control 6.0 (SP6) (OLEDB)". When I double click the resource in the Resource View I get the expected warning "One or more ActiveX controls are in the current resource (.rc) file. If you trust the resource file supplier, click Yes to initialize and use the ActiveX controls. Otherwise, click No to exit.*"

However, when I click "Yes" I get the following error message and the visual editor does not appear:

The ActiveX control "Microsoft DataGrid Control 6.0 (SP6) (OLEDB)" is not registered on this computer. Register the control and try again.

I am pretty sure I have edited this dialog before in VS2022, but cannot work out what has changed.

I have (re-)registered the control via the following at an Administrator command prompt:

C:\Windows\SysWOW64\regsvr32.exe C:\Windows\SysWOW64\MSDATGRD.OCX

However, this makes no difference.

Any help in getting the dialog to appear in the visual editor would be greatly appreciated! Thanks.

Visual Studio 2022 is a 64-bit application. Consequently, the dialog editor will not be able to use a 32-bit .ocx. Perhaps you can use an earlier version of VS (VS2019 was still 32-bit).
