Occasionally, you may want to install your PDF2XL software from the command line.
It's as simple as running the following from the command line:
msiexec /i "<installer path>.msi"
Be sure to enter the correct "installer path". For example, if your install file is in your downloads folder, it would resemble:
msiexec /i "C:/Users/myfiles/Download/PDF2XL-Setup-Full.msi"
If you include the /qn command, it should install without user interaction:
msiexec /i /qn "<installer path>.msi"
