For V7.5 issues:
To completely reset V7.5 to factory/install defaults, close all EFILive V7.5 software, uninstall, run "regedit" and remove the entire V7 registry hive from here: Computer\HKEY_CURRENT_USER\Software\EFILive\V7.5 then re-install.
You could try modifying the V7 Tune Tool desktop icon (right click and select properties) so that the "Target" field has a " /l" at the end. (that's space, forward slash, lower-case L, without the quotes).
Then run the tune tool "as administrator" by right clicking on the icon and selecting "Run as Administrator", that will create a StartupLog.txt file in the \Program Files (x86)\EFILive\V7.5 folder.
like this:
Attachment 22513
Try looking in that trace file to see if it shows any issues.

For V8 issues:
To completely reset V8 to factory/install defaults, close all EFILive V8 software, uninstall, delete the V8 install folder: \Program Files (x86)\EFILive\V8
and delete the three files:
Documents\EFILive\V8\Config\EFILiveScanAndTuneLayo ut.ini
Documents\EFILive\V8\Config\EFILiveHapi.ini
Documents\EFILive\V8\Config\EFILiveScanAndTune.ini
Try starting the V8 software by double-clicking on the V8 Scan and Tune desktop icon while holding down the Ctrl key on the PC keyboard. That will create startup log file(s) in the folder: \Documents\EFILive\V8\Trace called
EFILive_ScanAndTune_StartupLog.txt
EFILive_Hapi_StartupLog.txt
Try looking in those trace files to see if they show any issues.
