Hi Adrian; when I first loaded an Asset beta - I think it was beta-6 - the AssetUPnP-Data folder was in the Shared Folder. That install also had the link to the GUI. Then Asset crashed on me I uninstalled & went back to Synology Media Server. I then gave it another go & loaded beta-8, the AssetUPnP-Data folder was NOT in the Shared Folder, this install also did not include (show) the link to the GUI. I did not check to see if AssetUPnP-Data was there with beta-10 Now with beta-11 AssetUPnP-Data is in the shared folder.
I've too have been pondering how good this install is, does it have an issue, missing or bad links. The missing GUI link & 'Open' tab seems to indicate a bad install, so I've uninstalled (again). After uninstall I checked & noted the AssetUPnP-Data folder is still in the Shared Folder & I've also deleted this. Additionally with this uninstall I've included a system restart in an attempt to clear out any detritus that may be present.
Now with beta-11 install as per above: AssetUPnP-Data folder is NOT in the Shared Folder. There is NO GUI IP#:45537 link. There is NO 'Open' tab - only Stop & Uninstall. I had to go back into Configure to reset my preferences. Apart from that Asset works.
