v2.9.0.6 Ubuntu: unhandled Exception: System.Exception: GDfetch2.dll kon niet gevonden worden

[Frank58]

Ook nu bij Ubuntu de volgende melding. Ik heb er maar een apart onderwerp van gemaakt daar Linux toch wat andere benadering behoeft dan Windows 10.
Wie heeft de oplossing. Ik kom er niet uit.

Code:

Unhandled Exception:
System.Exception: GDfetch2.dll kon niet gevonden worden.
