Thanks a lot,

Answer 1

Most probably your user doesn't have write permissions for the C:\Program Files (x86) folder therefore you're getting this error.
Choose different location (you definitely have write access to your home folder)
Another option is to run JMeter as administrator, this way you get rid of WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0 error as well which unlock some customisation persistence.
Also be informed that according to 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article you should always be using the latest version of JMeter so consider upgrading to JMeter 5.3 (or whatever is the latest stable JMeter version which is available at JMeter Downloads page) on next available opportunity.

Answer 2

not being on Java8 was the problem for me.
Install Java 8 and it will run fine.

Answer 3

Try the following:
Open JMeter -> Options -> Look and Feel -> Select any other theme other than Darcula.
Restart JMeter,
Create test plan and
try to save.
Save should work.
