Iko Rein,
Would you please check 5.1. I download and unpack with 7zip and run java -jar telemetry.jar as administrator and it creates the fastest_laps, laptimtes, etc. directories but gives and error that it can't find settings/graph_settings.xml or /settings/settings.xml. The settings folder is empty. Version 5.0 is exactly the same. I know I had this working just the other night, so I'm kind of stumped as to what might have happened. 5.0 doesn't run and the settings directory is empty too.
java 1.8.0_60
Hmm, I never run this as administrator, as I keep the files in area (under \users\ or under \bin\telemetry), where it doesn't require admin rights. If you start the plain app, and then press CTRL-S, the system should create at least the settings.xml.
So I tested bit more. If you put the app in Program Files and run it without the admin rights, the system cannot write data to those directorie . So if you put it into the Program Files directory, you have two options:
1) You need to run the tool with elevated rights.
2) You edit the baseSettings.xml and either put set dataDir to userDir (files will be written to \users\<user>\telemetry or set some path with the Path!. This way the files can be written without the need to use elevated rights.
If you run the program from the command prompt with the java -jar command, you will see with a fresh install the error messages, because those files don't exist, when you start the Telemetry tool. If you do CTRL-S from the tool, then the settings file will be created and if you modify the position of the graphs and save them, then the graph-settings will be saved.
In 5.1. You can turn off the error messages by setting in the BaseSettings.xml the LoggingLevel to OFF. That is the default with 5.1.
//Cheers.
