Unity Pro Trial Upgrade

Greetings,

I installed the Free Version of Unity3D on my Laptop, also registering the Version as the well Free Version.

Now I would like to try out Unity3D Pro, but when I reinstall Unity I’m never presented with the Option to choose which Version I want to register.

Deleting and reinstalling has not been working for me and I am fresh out of Ideas. Can someone please show me a way so I can at least try Unity Pro?

reregister unity and then on the page choose the pro trial. given you have not used it yet (due to an error at the beginning) it will just work as pro for 30 days technically.

if you though did by error, contact the support to request a trial expansion, explaining your situation etc

Worked perfectly.
Thank you very much!
