Install doesn't work on Win7 / VB6

Run MapWinGIS-only-v5.3.0.0-Win32-VS2017.exe on Windows 7 but the component doesn’t show up in VB6

Try to manually register mapwingis.ocx and it gives error: “The module “.\mapwingis.ocx” was loaded but the call to DllRegisterServer failed with error code 0x80070005”

Any help would be appreciated
