Unable to start: System.Net.HttpListenerException: The process cannot access the file because it is being used by another process
0
My last successful install was 7.13. Everything newer (7.22, 7.23 up to 8.0.0 beta 3) installs normally but on start I get the above error. Deinstalling and reinstalling doesn't matter, deleting all .NET doesn't matter. I'm on a managed host and perhaps thats the problem, when I try ‘repair’ in the control panel it can't find the msi …. the folder it's supposed to be in is empty. It's a long shot but does anybody have any idea on what can be done or where I can investigate further?

In recent versions we introduced a WYSIWYG page editor into the Modeler. It runs a server on a random port for the web-based page editor to talk to. On your machine opening a port for listening fails for some reason. We have not seen this issue before.
Questions:
What operating system are you running?
Can you try running the Modeler in administrator mode to see if that helps?
Is your laptop managed by an IT department that perhaps added some aggressive security measures?
