We debugged and looks like the issue is an error happening while parsing the java version("1.8").
One possible reason for that can be that decimal separator on your machine can be other then a dot (.), so can you verify the decimal seprator in your system and let us know what it is. Here are the steps to find it out.
- Open "start menu" and start typing regional.
- Select Change date, time or number formats.
- Go to additional settings.
- Under the numbers tab.
- The decimal separator value.
If in case the decimal separator is not dot (.), can you change it to dot(.) and try out the installation again.
