Judging by the console message, this seems to be a different problem. If it was related to missing VC++ redistributable files, the application would have failed to do module loading, as shown in the screenshots above.

It is able to get past the module loading step, and the application starts rendering, but then it fails with "DevTools was disconnected from the page". This typically means that the application tried to run some native code, which crashed. This is unfortunately a bit hard to debug.

When the application starts, one of the first things it does is to look for connected devices. You could try to unplug all devkits before starting the application to see if it makes any difference. Also, check if something is printed to the log file in C:\Users<username>\AppData\Roaming\nrfconnect.

@andrewjfox Which version of Windows are you using? Do you see the same error in the developer console when pressing Ctrl+Shift+I?

I am also having this problem, but already had VC distributable installed. I've tried uninstalling/installing VC distributable and still get white/blank screen when Connect starts.

Yeah, this makes sense. On my Windows 7 machine I have Visual Studio 2015 installed, but the two other PCs are probably without VS2015.

RE: nrf connect 1.1 - white/empty window (PC version)

Magne Rodem — Fri, 20 Jan 2017 14:21:48 GMT

I have been able to reproduce this on a Windows 7 VM. It happens because the application cannot find Visual C++ Redistributable for Visual Studio 2015. This is bundled with nRF Connect, but apparently there is a problem loading the DLLs.

A workaround for now is to install Visual C++ Redistributable for Visual Studio 2015 (vc_redist.x86.exe) from Microsoft's website: www.microsoft.com/.../details.aspx

Can you also comment on if nRF Connect v1.0 was already installed when v1.1 was installed ?

RE: nrf connect 1.1 - white/empty window (PC version)

bjorn-spockeli — Thu, 19 Jan 2017 09:46:08 GMT

Hi Moritz, can you ask your colleagues to press ctrl+shift+i with the nRF Connect Window selected to open the developer console and then report any errors listed there in this question. Also was nRF Connect v1.0 already installed when nRF Connect v1.1 was installed?
