The Microsoft sign in is used for players who have bought Minecraft. If this error occurs:
You do not own the game, click 'Switch to offline mode' and enter a username that is not already taken by a premium user (use websites like namemc, search for your username and see if it's taken or not. Use if it's not taken).
You chose the wrong Microsoft account to sign in.
If you have already bought Minecraft and see this error, while using the correct account, restart the launcher.
Disable your AdBlock and try again. If you are still unable to download SKlauncher then try again with Incognito (InPrivate, Private) mode turned on. If the problem still persists then try to download sklauncher using different browser.
Try to delete folders from other launchers in
.minecraft folder, other solution is to delete sklauncher folder in
.minecraft and install it again.
If the solutions above doesnt work, check Firewall or your Anti-virus program, it might block Java from running. Update Java to required version.
Check your sklauncher logs text file and look for 'DNS Poisoning', if you have this issue, run antimallware software.
After it finishes, disconnect from your wifi, look for a file
hosts located in
C:\Windows\System32\drivers\etc, edit it with notepad++ and delete unwanted dns text lines without # at the beginning of the text lines.
If you done it properly, run
cmd as administrator and type
ipconfig /flushdns, it will flush all DNS to get rid of any potentially malicious entries. You should have something like this after you flush your DNS:
Successfully flushed the DNS Resolver Cache. After that just restart your pc, connect back to wifi and run sklauncher.
If it still does not work delete .json files of the launcher and run again
