New Version Mono errors

[geffers]

Folks,

Been running VRS v 2.4 on Linux Ubuntu 16:04 for some time with no problems.

Due to getting Google map problems I've tried to upgrade to 2.4.2 and get errors on mono. Ran the complete installation again of mono as per your web page instructions and it appeared to install with no problems but on trying to run I get the following error;

Code: Select all

sudo mono VirtualRadar.exe 
WARNING: The runtime version supported by this application is unavailable.

If I run the same command with the old version VRS 2.4 runs fine with the following error output from mono;

Code: Select all

sudo mono VirtualRadar.exe
WARNING: The runtime version supported by this application is unavailable.
Using default runtime: v4.0.30319

Any suggestions welcome.

Appreciate 2.4.2 is relatively new so may be a few bugs, particularly in the Linux version.

Return to the Linux page on the web site and read the "Mono 4 Issues" section.

Thank you, that worked perfectly.

Hi there,

I am getting the same error message even with having the config VirtualRadar.exe.config file in the same directory.

Do you want to use VRS in headless mode?

Then you need to add the "-nogui" parameter.

[TheTwist]

I'd prefer to have the GUI. I am new to command line.

[Datamix]

If you want to start VRS with a GUI then you need a OS which has a GUI system installed (like X-Server, see you error message).

[TheTwist]

Oh okay, I am using a Raspberry Pi thought the GUI would work

[Datamix]

I think it would work if you use "Raspbian Stretch with desktop".
