Your Bajoo client, on Windows, may fail to launch with an error message stating that the file “api-ms-win-core-crt-l1-1-0.dll” is missing.
Its absence is abnormal and is not related to Bajoo.

To correct this problem, reinstall “Microsoft Visual C ++ 2015 Redistributable Update 1”:

Download the 64-bit (x64) version if you have a Windows 64-bit installation or 32-bit (x86) if not.
To find out your version, go to “Control Panel> System”: the operating system must be 64 bits (the processor will necessarily be in this case) to claim the use of the x64 file.
