Since TARS issues are more common lately here is some reference for anyone that might have a problem.
Make sure you have a backup of:
export.lua - Located in DCS_INSTALL_FOLDER\Config\Export
TS3client folder - Located in C:\Users\YOUR_USERNAME\AppData\Roaming
or
config folder - Located in C:\Program Files (or x86)\Teamspeak 3 client
It's imperative that you have backup of TS3 personal data before you proceed!!
Download Teamspeak x64 3.0.3, x64 3.0.5 and TARS. Working under assumption that you run x64 operating system.
Also I'm providing the original export.lua and my Export.lua files.
This way you have all the files you need at hand. Some people reported that 3.0.5 is not working for them. Hence the 3.0.3 link.
If there is already existing installation of Teamspeak and TARS and you are experiencing problems then what you want to do is:
Uninstall TARS
Uninstall Teamspeak3
Erase TARS and Teamspeak 3 folder from C:\Program Files
Erase or remove TS3Client folder located in C:\Users\YOUR_USERNAME\AppData\Roaming
Triple check or restore Export.lua file to default or previous working version.
After you are done removing, start to install everything back.
Install Teamspeak 3
Install TARS
Open up TARS control panel AS ADMINISTRATOR
Configure TARS (plugin installed, A-10C set-up, guard, keys, etc)
In teamspeak 3 go to Settings > Plugins and make sure TARS plugin is checked
Triple check Export.lua as last line should read dofile("./Config/Export/TARSExportA10.lua")
Couple of tips:
Make sure you have latest drivers for the HOTAS! The TARS was not registering MIC switch presses on TM WH Throttle until drivers were updated.
Always run TARS control panel AS ADMINISTRATOR - see here run-as-adm.jpg. This way TARS can write to some files that are located in TS3 and DCS folder.
TARS control panel does not need to be run along with TS3 and DCS.
You are not required to run DCS or Teamspeak as administrator. But never run one differently then the other! You were warned!
Should any of you still encounter problems feel free to contact me (preferably on TS) for some more brainstorming or even remote help.
