Jar2Exe Activate

Activate Jar2Exe after purchased


After purchased, you need to activate Jar2Exe before you use Jar2Exe to generate exe files for redistributing. Activated Jar2Exe will authorize generated exe to run as a product.

Orders are processed automatically and immediately. After purchasing, you can "Activate" Jar2Exe with your "username / password" and you can also create your "register user / key" at http://www.jar2exe.com/regkeys/ .


Once purchased, you can "Activate" Jar2Exe with your "username / password" of your account at this website or "register user / key" created from http://www.jar2exe.com/regkeys/ .

Please note that, if you activate Jar2Exe using "username / password", internet is required. The program will open http://www.jar2exe.com/regkeys/ and create a "register user / key" and use that key automatically.

License type exchange

Hello, I had purchased the Personal license and had already registered and activated the program.
Today I bought the Standard license, I already created the key on the site, how do I change the key in the program, because it keeps giving the message "The generated exe file is not authorized to be redistributed"

Please use the key to activate Jar2Exe

Please use the key to activate Jar2Exe or activate Jar2Exe online using your username/password.

Then at the last step, please check the checkbox "authorize".

I can not activate my purchase

Hello, I bought the Standard license (USD 145) without having previously created a user.
I already have the confirmation email that indicates the serial number and the name of the user.
As they ask me to log in to activate my purchase, I have registered using my same email, but I do not see the registration key.
Using the same program Jar2Exe I enter the user and serial but it generates error.
Help me please. Thank you
