I have the same problem, I dont know how to open the houdini engine for users that doesnt have houdini installation

the file i am using comes from tutorial https://www.sidefx.com/tutorials/sci-fi-level-builder/ [www.sidefx.com] and its already been build by using old curve. So unfortunatelly is a different bug

Hi Im evaluating Houdini workflow for my company, im going trough the Sci Fi Level Builder tutorial, while ive been testing the HDA attached to the project files, I noticed that in unity 2021 the curve tool wasnt working. So i updated my unity to 2022 and I exposed the parameter again. It worked, but during my short presentation the houdini engine curve menu in unity disparead.
I restarted my unity and it wasnt working again. so i restarted my pc but that didnt help either. Next time i opened steam firsts, and launched pipe session, after i opened unity before i clicked on hda in my scene i tried to connect to pipe session, but error apearedit tells me to check if pipe session name is valid. but i dont know what it compare it to. Houdini is installed in specified location.
To check if this HDA is somehow corrupted i've opened houdini engine tools from houdini engine menu, and selected curve instancer- create tool. this didnt created curve either
The Green curve is still visible in my Level_Builder_Tutorial_File_1_2 but i cant see the menu that allows me to add, or edit points on the curve
Ive looked on the forum and Ive found two solutions. one is to upgrade unity which i did, the other one is to use old curve node. Which I enabled in Shelf Tools and Tab Menu and select >Show All Operators. but im not sure which node to select

Can you please help to achieve stable usage of the curve menu option? Should I change my unity version and if so to which version, connect differently with pipe sesssion(if so-how?) or use different curve node(if so, which one?)
