i have done that already even though i am facing same error
Hi i have added my turbofloatserver on VM and want to activate via offline so has uploaded activation request of that product and allowed VM activations also even though it is stating can't activate on virtual machine
Edit the product key and allow VM activations. It’ll give you a big red warning to *not* do that.
Make sure you actually save the changes.
