Hi Expers:

After my Sage 50 2018.2 SDK installation on Windows 10 I got problem when I tried to create a Login Object by COM:

Unable to cast COM object of type 'System.__ComObject' to interface type 'PeachtreeAccounting.Login'.

This operation failed because the QueryInterface call on the COM component for the interface with IID '{68570996-0A96-4F39-9ED1-2443770194DC}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

I search the IID '68570996-0A96-4F39-9ED1-2443770194DC'  and Data 'ILogin'in my register and the Key doesn't exsited at all.

And the Sage 50 Smart Posting Service doesn't deployed as well so I deployed it as a Windows Service manully.

Windows 8.1 doesn't have this problem. Could you please show me a way to solve the problem on Windows 10?

Thanks

Billy
