I am having the same problem.
I can successfully "Online test" but when I try and Remote access to the PLC it comes up with:
Run-time error '5':
Invalid procedure call or argument
and once i click "ok" visilogic closes.
I am running 64bit windows 7 I am trying to connect to the PLC via ethernet. The PLC is V1040.
I have re-installed Visilogic 9.3.0 twice as per the removal procedure in this forum with no luck correcting the issue, to make things worse this function works fine accessing the same project on a collegues computer hence I am thinking something has fallin over in my puter.
What am I looking for? This is "Bugging" me (excuse the pun), as I will be required to remotely control this through the access portal in a short while.
