Nope
I have tried all of that other than deleting line for a runtime code that Frontier has not removed that can cause the update error. But he doesn't say which line of code on the launcher is removed so I can't do that. Hope the admin flags support for me.
The editing you refer to is as follows:
In your EDLaunch directory - make a copy of the file "EDLaunch.exe.config" and stick it somewhere safe in case of issues. Then edit the original file "EDLaunch.exe.config" (notepad will do), you will see the lines:
<startup>
<supportedRuntime version="v2.0.50727"/>
<supportedRuntime version="v4.0"/>
</startup>
Just delete the line " <supportedRuntime version="v2.0.50727"/> " - save and start the launcher.
If it doesn't help then you have some other issue, sorry.
NOTE - this forum software removes the blank spaces so the layout in your config file will (probably) look different - it isn't a problem.
BTW - If you are not getting emails to acknowledge a ticket then there must have been a problem creating the ticket (a captcha issue for example) - you should also be able to see your ticket on the support website - if you can't then it didn't get created (or you made it a bug report).
