I have error during install. 
Hello @Mugz Have you tried downloading the installer again, but with a
different browser and/or on a different computer? Regards, Boris
I tried download via chrome/edge/wget - no luck. I dont have a different
computer. Will try at work, but all other installers work perfect
Redownload from another computer and all now installed correctly. Thanks
Thanks for the feedback, Regards, Boris
I got a similar error downloading the SDK 0.21 (cab1.cab was corrupt). Tried
different browsers (edge, chrome, firefox) with or without MSFS running.
Chrome started downloading fast then at some 20% rate dropped to some KB/s
below ten and remained there. Took ages to finish and the download failed
several times. My internet connection is/was pretty good, could stream Netflix
and several Youtube videos the same time in highest quality (tried it after
one of the downloads failed) Servers were operational all the time. Same with
firefox. Edge couldn’t even open the download page on first try. I finally
managed to install the lasted SDK version by using a dropbox link someone put
on the official MSFS forum <https://forums.flightsimulator.com/t/link-to-
