Installing v17 Standard after testing Pro version

Hi. I bought a v17 Standard license. After that I was offered a one year v18 Pro for free. The year has now passed and I want to go back to the v17 Standard that I bought. I deleted the v18 Pro and downloaded the v17 installation DMG. However, this DMG only installs the v17 PRO version and my v17 Standard license will not work with it.

How do I install the v17 STANDARD version?

Thanks.

edit: I got this to work with help from the Parallels support. Turns out I was entering the licence using cut/paste which included entering the hyphen ("-"). However, the license entry field is only expecting the key values. It puts in the hyphen automatically.
