Unable to install New version instance when old instance exists

[Borgas]

Hello!
We have a product that installs with multiple instances. Eg Customer1, customer2, customer3, etc.

We have solved this by using instances. The problem is that if I want to install a new customer with a newer version, this is not possible as the choice is not available.
Eg Customer 1 Version 1, Customer 2 version 1, New customer version 2, How can this be solved?

Hello Boris,

From what I can see, you have an ongoing thread with my colleague Eusebiu over the email.

If possible, please continue it over there so we avoid duplicate threads.

Thank you for your understanding!

Best regards,
