I am using Magento version 2.1.7.
When I install an extension in my magento it doesn't check php version.
Earlier it show that cron hasn't been configured yet error. For that I changed the cron check & updater check as 'success' to skip the checking of cron.
Now it is not checking the php version in my system.
My php version is 7.0.2 & I have set the memory_limit=1024M in php.ini file.
I am using XAMPP for the apache in windows.

I am putting this answer that How it worked for me.
Went to Magento Directory opened CMD there & Ran below commands. To run the cron separately.
Than ran the readiness check again & it worked.
