The Activation key of InstallShield 2020 can't work
We have a Activation key of InstallShield 2020, but our PC installed InstallShield 2019, so far the InstallShield 2019 is not able to be activated with the key.
Because we don't want to upgrade InstallShield 2019 to InstallShield 2020, any helps?
Please reach out to the support team who will be able to help you with this, they should be able to check your license and help you in activation- you can contact them directly via phone using the details at this link:
Alternatively there is an online chat available which you can find in a clickable box image on the right hand side here:
