Agreed, the installation process did not go smoothly for me either. On starting the installer, the default stream was "TNI Physics", and I was advised to "use the default stream". Curious, I clicked "Install", and of course got the "No patch available" message.
I then tried the TRS22 Beta stream. It started out downloading quickly, but then slowed waaaay down until the estimated time was 6-hours-plus. It then failed with a rather tangled-looking error message. I re-downloaded the installer and tried again, and this time it succeeded.
Inside TRS22, I thought I would try one of the philskene routes. I clicked 'download', and it proceeded, but when it got to the unpacking stage, this failed, with a series of error messages. I could still open the route, but it was (of course) missing a lot of assets. It also did not show up in Content Manager, so I don't know how I would go about deleting and then re-trying the route.
Just my 2 cents, for now. I watched the video by Approach Medium with great interest, and overall I am extremely impressed with the way Surveyor 2.0 works, and am looking forward very much to using it myself.
