I just tried to install Directory Opus V12.20, present version is V12.19.
The installation fails giving the error "Runtime error (at 15:1564): Could not convert variant of type (Null) into type (OleStr)". The installer then enters a hangup situastion. The installer is 36,6MB.
I downloaded installer DOpusInstall-12.20.exe (36,6MB), this gave the same result.
I have the old installer stored on my PC (55,2MB), can I use that one?
