this is a known issue. Sometimes the runtime detection doesn't work - especially when Visual Studio is installed. In this case, check the box "Do not show this again" and hit OK. All should work then.
We are also working on a version where the VC runtime is not needed anymore.
I'm getting an error icon when trying to open a VNC connection, saying that the Visual C++ runtime is not installed. I downloaded and tried installing the x64 version just to notice that I do have it installed, in fact a newer version than the one in the download page that the button took me to.
Also, if I click OK in the dialog with the "errors" and download prompts, I'm actually able to connect successfully.
So the seems to be that Royal TS is not detecting the Visual C++ runtime (maybe only certain versions of it?). I imagine the newer version that I have installed might have come from either of these:
- Windows' Fall Creators' Update.
- Visual Studio 2017.
