Why does installing Rtools42 generate Windows setup error?

When installing Rtools version 4.2 on Windows 10, I get a pop-up window with the following message at the end of the installation process:
Unable to execute file:
C:\WINDOWS\system32\cmd.exe
CreateProcess failed;code 2.
The system cannot find the file specified.
The only thing I have done previously is to install R (version 4.2.1.).
I fear ignoring this message will lead to issues later on.

Meteor installation/updation problems on Windows 7

I'm tried to install Meteor on Windows 7:
I downloaded the installer from the official download link. Upon trying to install it, I get the error Failed to contact install server.
Using this answer over here I successfully managed to install an older version of Meteor: but now neither meteor update nor any other command works. The response I get is:
This project uses Meteor 1.2.1, which isn't available on Windows. To work with this app on all supported platforms, use meteor update --release METEOR#1.2.1 to pin this app to the newest Windows-compatible release.
The suggested command generates the same response. Any workarounds?
