In this video i am showing you that how can you fix NSIS error in windows during software installation.
Remember open CMD as administrator.If you still face error then follow this step:
Go to start and write CMD than hit enter. A black window will be opened. Now go to the folder where the .exe file is. If it is in a disc or a pen drive then copy it to your hard disk. Now drag the file to the black window or the CMD window and you will see that the address of the .exe file has been copied to the cmd window. Now on the CMD window- press space and write /NCRC and hit enter. You will see that the installation window has been opened. Then you can install the software.
