Custom action

[Ken487]

My installer uses a custom action in a standardard DLL. The action is only called during a patch, and is used set a launch condition to false if the user's license is not valid.

It works well and displays the error message I created. However, when the installation aborts, the installer displays the 1603 error message, "network file not found".

How can I stop that message from being displayed?

Thanks in advance,

Ken.
