Ok, we are talking about different execution contexts here and two different problems:
If you want to use the
Desktop Macro Task you need access to the desktop. There are a couple of ways to do that:
1. Never log out on your server - just keep it locked
2. Add and select a Credential in Execution Context settings in the main settings of VisualCron (button Change).
If you want to use a normal
Execute Task and get the error you describe you are probably trying to run the macro from a network drive. You need to:
1. Specify a UNC path (\\server\folder\file)
2. Add and select a Credential on remote server.
