Many users can't launch Skype because of this Javascript error
Plenty of users recently started reporting that they are having problems installing and using Skype after the latest update.
They are complaining that every time they try running Skype, they are met with an error message.
I downloaded Skype-8.38.0.161 using Windows 7. I installed it. But the program did not open. Instead I got an error message ‘a JavaScript error occurred in the main process’.
While the majority of problems seem to apply to users that have Windows 7, there is also a chance for this error to occur on Windows 10 as well.
