OS: CentOS 7.

I wanted to start vmplayer from the terminal, but was given a message: 'Before you can run VMware, several modules must be compiled and loaded into the running kernel'.

I clicked install and both, vmmon and vmnet were installed; however when VMware started up, there were error messages in the terminal.

How can I be sure that these errors won't cause problems down the line?
