Setup 
When you run the Setup, the software will be unpacked into the EaseUSDiskCopy5.5 folder along the path C:\Users\User_Name\AppData\Roaming (the AppData folder is hidden; you should make all the folders visible)
After unpacking the application starts and needs to be registered.
You can get a License Code for 1 year here (use any temp e-mail for registration)
After successful registration run the software by double-clicking the same installation file from anywhere or you can create a shortcut and run it from the Desktop.. You can also create a bootable disk to run the software from a flash drive.
If after using you need to remove this portable version from your PC just delete the installation file (if it"s on your PC), restart your machine and delete the EaseUSDiskCopy5.5 folder from the C drive in normal way.
