Hello! If CopyTrans is not opening, please add CopyTrans programs as an exclusion to your antivirus. You will need to add this folder: C:\Users\*YOUR USERNAME*\AppData\Roaming\WindSolutions. Do not forget to change the *YOUR USERNAME* to the one that you actually use.
After you've done that, please turn off your antivirus and keep it turned off while using the program (it is important to both add the folder to exceptions and turn the software off). We also recommend adding CopyTrans software as an exclusion to your Windows Firewall and your Antivirus Firewall (if you have it).
