Installation of UniFlash 3.1.00026 on a machine with Visual Studio 2013 or above already installed fails. UniFlash tries to install the Visual C++ 2012 Redistributable package, however since the 2013 redistributable is already installed (due to VS 2013), this causes the 2012 redist. install to fail (with an error dialog noting that a newer version is likely present). Unfortunately this also brings down the entire UniFlash install.
It would be nice if UniFlash was updated to resolve this issue. It seems there are few alternatives for flashing firmware over XDS100s without having a CCS project for it.
