Onyx doesn't see network drives

1. In Registry Editor, locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
2. Right-click Configuration, click New, and then click DWORD (32-bit) Value.
3. Name the new registry entry as EnableLinkedConnections.
4. Double-click the EnableLinkedConnections registry entry.
5. In the Edit DWORD Value dialog box, type 1 in the Value data field, and then click OK.
6. Exit Registry Editor, and then restart the computer.

I think this is what fixed it for us.

 

I think I had that issue when running the app as administrator.
If you're doing that try just running as a user.

 

Worked for me as well with Onyx21 Postershop when upgrading from version 12. I could see the network fine with old version but after upgrade I lost the mapped drive. The registry edit above fixed the issue.

 

Have you got Onyx running as Administrator? That could be your problem
