When installing from TI Resource Explorer in CCS, the Linux (or mac) version of the pre-postbuild tools (lib-search, oad etc) is installed, instead of Windows version: Executables have no .exe extension, meaning example projects fail to build out-of-the-box.
When selecting a Windows installer from the webpage separately and installing from there, this issue doesn't happen. Downloads can be found at www.ti.com/.../SIMPLELINK-CC2640R2-SDK
