Activation Wizard is disable to input License

After use 30 days for trials, now my RobotStudio is not let me click to Activation Wizard to install the new license.
Even I have the new premium license, I can do nothing to input the key!!! I tried to uninstall and re-install RobotStudio 2021.04 but still not work.
Does anyone know how to fix this problem?
Thank you!

Hi! I realize that this question is old and you probably already solved the problem but for future reference, the solution to a grayed-out activation wizard please follow these instructions:

Execute the command below which will delete the 7.x folder:
RD /S /Q “%programdata%\ABB\RobotStudio\7.x”

Then execute the command below which will recreate the 7.x folder and reinitialize the license storage:
“%programfiles(x86)%\ABB\RobotStudio 2021\Bin\RobotStudio.Installer.exe” -InitLicenseStorage

At this point when you start RobotStudio the error should not appear and you should be able
to access the license activation wizard.

For a quick answer to licensing questions, you can always send an email to softwarefactory_support@se.abb.com

Have a nice day!
