Spring boot suite error, please help


i have installed spring boot suite and i have an annoying error that i havent had any luck with so far.
this is the error:

i tried adding -vm and path in the STS.ini file like this but still showing error:

my lib folder didnt have a tools.jar file so i downloaded one and added it to the lib folder but still showing error.
changed a few other things as suggested on SO but still no luck so far.
