If the product is registered, the watermark (www.BANDICAM.com) will not be added to the recorded video and the recording time will be unlimited.
Once you purchase the program, there is a lifetime guarantee on the license as long as you follow the license policy.
Even if you do not use Bandicam at the same time on 2 different computers, you must purchase a 2-PC license to use it on two devices. If you want to use a 1-PC license on another computer, you must either uninstall the existing registered Bandicam or upgrade the maximum license count at https://www.bandicam.com/buy/upgrade/ (1-PC upgrade = $27.79).
If you unregister Bandicam or your computer is broken, you can re-use the license on another computer.
Once you have registered the license, you cannot change the email address or the serial number. You will not have any problems as long as you keep the license information and follow the license policy. If you want to change the email address or serial number, go to https://www.bandicam.com/buy/upgrade/, upgrade the maximum license count, and then contact bandicam@bandicam.com.
Go to https://www.bandicam.com/buy/ and enter the email address used for purchasing the license at the "Resend Purchased License" section. The license will then be sent to your email again. Please send your payment receipt to bandicam@bandicam.com if you forgot or cannot access your email address. If you don't have the receipt, you must repurchase the license.
