Widespread software piracy has made this system necessary.
When you open the Batch Processing window the first time, DupeNuker will try to verify your username with our authorization servers at techsono.com and techsono2.com. This usually takes less than a second. The servers are at different locations and you only need to be authorized by one of them. So, if there is a glitch somewhere on the internet, or one of the servers is down, the other server will authorize you.
If you have a firewall, you may need to configure it to allow DupeNuker to access techsono.com.
After a failed authorization, you will have to restart DupeNuker.
If you still have problems, go onto DupeNuker’s “Help” menu and use the “Open App Data Folder” command. In that folder, open the file named “auth-debug.txt”, copy the text into an email, and send it to the address on the Support page. Also include the email address and registration key that you have entered into DupeNuker.
