Because it is an ActiveX control all versions should be compatible with VB6. But do you really want to create a VB6 application? Canā€™t you move to [VB.NET](http://VB.NET). It will make your work much easier šŸ˜‰ ---

Hello @PaoloM I canā€™t say why itā€™s not showing up in the Components list. Even so, when opening an existing project that has a reference to an earlier version of a component, VB6 will automatically update the version within the Project and Form files. Since the GUIDs are the same, VB should see the newly installed OCX (although you may want to make sure the files are not read-only when you open them). Another option might be to open the previous Project and Forms in a text editor, like Notepad or similar, and just add/change the references in the files. Within the Project (vbp), you should see something like Object={C368D713-CC5F-40ED-9F53-F84FE197B96A}#5.2#0; MapWinGIS.ocx and within the Form (frm), you should see something like Object = ā€œ{C368D713-CC5F-40ED-9F53-F84FE197B96A}#5.2#0ā€; ā€œMapWinGIS.ocxā€ Set the version number based on the OCX you have installed; just donā€™t enter a number that is higher than the version you have installed. I hope that helps. Jerry. ---

Hi @PaoloM I was in the same situation. Register the OCX manually using regsvr32 as any other OCX/DLL you wrote in VB6 First unreg the old one and then register the new ---

MapWinGIS-only-v5.3.0.0-Win32-VS2017 is the latest one And the reg command is: `regsvr32 C:\dev\MapWinGIS\MapWinGis.ocx` or update this lines into regMapWinGIS.cmd ```auto REM Unregister any previous versions: regsvr32 /u C:\dev\MapWinGIS\MapWinGis.ocx REM Register current version: regsvr32 C:\dev\MapWinGIS\MapWinGis.ocx ``` you can use only the OCX name, but remember copy it into SYSTEM32 directory registration complete: ![1](https://global.discourse-cdn.com/free1/uploads/mapwindow1/original/1X/0091e803b04641dd58b51d4abcec22978216af2a.png) Map version at VB6 ![2](https://global.discourse-cdn.com/free1/uploads/mapwindow1/original/1X/fb6dbd034cb995023452e351d23ff8cfd52124de.png)
