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 the 1-PC license on two computers, 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 uninstall/unregister Bandicam, format your computer, or your computer is broken, you can re-use/transfer the license to another computer. (We highly recommend you unregister Bandicam
before formatting.)
Once you have registered the license, you cannot change the email address or the serial number. However, if you upgrade the license and send an email to bandicam@bandicam.com, the manager will handle your request.
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.
