hanks for your message.
As I have explained to Takeuchi-san last night, I did not see the error message.
I am running NiceLabel Automation. The Windows Service is running under my user account (domain user account).
I am able to count number of lines in the trigger file without such permission issue.
Before we investigate further,
1. Have you tested my sample with NiceLabel Automation? Do you see same problem?
2. Is your NiceLabel Automation (or GalleryWatch) services are running with your user account (or domain user account) as you are logged in?
