Hi,

Yes, you download the trial version. This download version will become a trial version if used without a license. With a license it becomes a licensed version.

Kind regards

Your V18 license works for every TIA Portal version up to and including V18 (so V17 will also work with a V18 license).

I have TIA V18 Portal along with STEP 7 Professional (floating) license, i need/want to download V17 Tia im just wondering do i download the trial version and then my licenses will take over after trial? or is there a specific Tia V17 i need to download sense i have the license and V18 already?
