I have downloaded and succesfully installed Flash Builder 4.7 from Adobe today and it all works apart from when I try to debug a project that is using the 4.6 SDK.
I get the message
Process terminated without establishing connection to debugger.
DVFreeThread - CFMachPortCreateWithPort hack = 0x3420c0, fPowerNotifyPort= 0x335200
invalid application descriptor: Unknown namespace: http://ns.adobe.com/air/application/21.0
Having looked at this similar question from 2015 it appears that my SDKs are all fine.
What is worrying me is that the error message is quoting a url that no longer exists -> http://ns.adobe.com/air/application/21.0
Does anyone know if Flash Builder 4.7 still works and is still supported by Adobe?
Thanks in advance.
