I dont know if this is the correct place to ask this question, I know nothing about visual basic!
I have win2003 server, (new from dell, pre-installed) I am trying to install 'sage manufacturing' it worked ok on 200 server, xp & vista. when I run the program it gives the following message:
vbalexplorerbarlib run-time error 91, object variable or block variable not set.
i have tried re-install, remove/install. its still the same. i cannot find what it wants?
any ideas.
