Some times, when you install software you will get a error message /”NSIS Error, Instraller integrity check has failed. Common causes include incomplete download and damaged media. Contact instraller’s author to obtain a new copy./” I’m trying to re-download the software but problem was not solving. so i have found a easy method which solved my problem. I have tried with windows 10 but i think it will also work with Windows 8, 8.1 and 7.

Jus Open your CMD and run like below:
/”Your software folder location//your software name.exe/”[space]/NCRC
