Hello,
The installation program might be having issues with proxy or firewall settings. You could try to download/install runtime and application in two different steps. Please try following:
1) Download runtime from http://software-dl.ti.com/ccs/non-esd/gui_composer/runtime/gcruntime-2.0.6-windows-installer.exe The one from the link above will contain an .exe named “gcruntime-2.0.6-windows-installer.exe”.
2) Run the DRV888x GUI installer.
3) Choose appropriate application and runtime locations, but avoid spaces in the runtime path name.
4) If you see the following screen during installation, then select the “Install from file” option, press the browse icon to the far left of this, and located the runtime installer named “gcruntime-2.0.6-windows-installer.exe”. Your screen should look similar to the screen capture below(except actual runtime installer version)
5) Press next and follow the instructions to complete the installation.
Martin
