I have noticed that about every third time or so I start up the VB6 IDE, a message box appears with the following error message:-
Method \'~\' of object \'~\
I found the ultimate solution!
To avoid the "Method '~' of object '~'" message and avoid any "Windows Installer" message from running at startup of the VB6 IDE:
With these settings it is OK to load any of the Add-Ins (including Visual Component Manager 6!)
It took me ages to work this out, but now VB6 loads with lightning speed and no annoying error messages.
