As per my knowledge, Eclipse 2015 still have issue with its cracked license
but i can share the similar installation procedure for eclipse 2014
go to file ecl141.7z and by clicking setup.exe [install Eclipse (will take few minutes)]
go to Eclipse 2015.1 crack.rar file and extract the whole files then copy and paste them in the following direction
C:\ecl\2014.1\bin\pc_x86_64 OR *:\ecl\2014.1\bin\pc_x86_64
Go to flexlm file and extract it... copy and paste the complete folder flexlm in the C drive ( C:\flexlm )
edit the license (Eclipse20141.lic) with notepad and change the name "Rashid" according to your PC name (NOTE: my PC name is Rashid so your PC name should be SINGLE English name e.g "Wang".. not acceptable as "Than Wang")
Copy MACAddressChanger from Eclipse 2014.1 crack.rar file and paste it in flexlm forlder in C Drive
run MACAddressChanger as administrator and choose the active internet adaptor and copy and paste the MAC address from the license (001e4ff152b5) and then click on change MAC ID
