Hi and welcome to Arturia forums.
FYI: This forum is for older Analog Labs placed in the legacy part of the forum. There is a current Analog Lab forum up the site.
The file vcruntime140_1.dll is a Windows program extention. Can you find it in the C/ Windows/ System32 folder?
You should probably have more than one vcruntime extention.
The messages i think refere to install the vcruntime140_1.dll again - not Analog Lab 4.
I assume your Windows 10 is fully updated. I'm not sure if a sfc/ scannow run as administrator will and can repair this, but i can suggest you try.
If you still after this have'nt got the .dll file, then you can try to download and install the Visual Studio 2015, 2017 and 2019 vc_redist.x86.exe and vc_redist.x64.exe from here:
https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads , and see if that helps. I'm a user, and i can't tell for sure.
BTW: I've never had a keyboard of any kind, where the sustain pedal was included.
Keylab essential is powered through the USB connection. The sales site mention the PSU connection is optional. It is'nt mentioned in the main features list. I agree, that it could be more clear, that the PSU is'nt included, if one need it though. A USB cable says to be included, but not a PSU. It could be said specific, that the PSU is'nt included.
I hope you'll get your issue solved, and you will enjoy your new controller.
