Step 1 - Try It You can use the program free for 30 days to see if it suits your needs. If you use it beyond 30 days you are obliged to pay the license fee. Please read the License Agreement for details. If you do not obtain a license key for the program, it will stop functioning after 30 days of use (rather than 30 days from installation). Step 2 - Buy It To purchase a license, please visit our online shop: www.scootersoftware.com/shop Step 3 - Unlock It Once we receive your order, we email you back with your license key that unlocks the program. When you receive your license key, copy it from the email message to the clipboard. Then start up your copy of Beyond Compare and pick Enter Key from the popup window that first appears, or, pick Beyond Compare > Enter Key. The license key disables the "nag" screen and removes the 30 day limitation. Your license key will work with all language versions of Beyond Compare 5, as well as all subsequent minor version updates.
