edrFTPnetPro does not work in production version of app.

Question

I have written an app for automating uploading of specific file to various FTP servers.
Some of the servers are SFTP.

The application works perfectly in the development environment.
However when deplying the application the production version does not work.

I was hoping to see it work in the production environment prior to purchasing. I need to ensure there are no security issues such as requiring elevated rights on the workstation. If that is a requirement then this API will not work for me.
I love the simplicity and the power provided with the API. I am really looking forward to purchasing it.

Environment information:

Development machine:
Win 7 Ult 64 bit
VS 2008 (Latest SP) VB.net is used for program.

Production machines:
Win XP SP 3
latest dotnet updates.

All other apps I have developed for this environment work fine, Only the FTP doesn't work. It seems to connect then disconnects.
Error Message = 'Control channel unexpectedly closed ( read so far) '
I am using the properties to set the License information.

Answer 1

Please enable logging at the All level and email the log file to support at enterprisedt dot com.

Also check that no firewalls are on the production machine preventing FTP connections.

Answer 2

These workstations have no firewalls enabled. They are behind a firewall of course. But the corporate firewall does allow FTP traffic outbound.
