Hi,
this might be a fairly stupid question, but advice would be welcome.
We've produced a simple VB6 app that talks to a Silabs UART->USB device via a virtual comport. We've pacaged it with the satndard deployment wizard to result in a silabs DLL being placed in the target installation directory (silabs says this required.
When installed on a new machine it works fine for administrator accounts but generates DLL errors (can't open port) for user accounts.

Any advice?

Many thanks,

Mark.
