Sorry for not updating this post - I have been extremely busy lately but I should have written a short post regarding how it worked out for me.
Long story short: thanks to , and all the people he got me in contact with, the problem has been solved for me at least. The team assessed the issue very promptly, and sent me a config file via email. With this file I have been able to install Kiosk mode successfully. In addition to this, they also very professionally noted down my criticism regarding the instructions pdf, and they said that they will make sure to update/improve this.
If I recall correctly, the people that I exchanged emails with stated that it might take some time to solve the issue with downloading the config file, which is why they made a config file for me and sent it to me. , perhaps Tony/the team could help you with this? Just as a side note - although Tony and the team have been absolutely great, the "actual" VIVE Enterprise support ticket that I started way back has still not led to any progress. I got an email the other day asking me to check if my 2016 MacBook Pro is "VR-ready", questioning whether perhaps it is my computer that is too weak to download the 122 kb text file. This is after explaining multiple times that I have tried downloading the config file using 5 different browsers on PC/Mac/Ubuntu.
