I have an application that has 2 forms with text boxes/combo boxes and command buttons.
I have packaged the app up including mdac.exe and ado 2.5 library, when I install it on numerous lap tops and some desktop pc's it works fine but on some machines when I click a command button that reads an access database I get an error 430 'Class does not support Automation or does not support expected interface'.

I dont understand why it works on some machines but not on others, any information as to a solution for this would be very much appreciated as it was due to be up & running by now and because of this I cant distribute it.

Thanks in anticipation
