Unable to install msp430-gcc on ubuntu 14.04

Hi

I am using ubuntu 14.04 64 bit on virtualbox on Windows 8.1 64 bit host.

I have to build some project and the project uses cmake system. I need to cross compile my project for cc430f5137 and for this i require msp430 gcc.

I downloaded the msp430-gcc-full-linux-installer-3.2.3.0.run file as mentioned here .

when i downloaded then I did

sudo chmod +x msp430-gcc-full-linux-installer-3.2.3.0.run

then when I type

./msp430-gcc-full-linux-installer-3.2.3.0.run

nothing happens and I get a new line on terminal.

if I type

sh ./msp430-gcc-full-linux-installer-3.2.3.0.run

then I get the following error

./msp430-gcc-full-linux-installer-3.2.3.0.run: 1: ./msp430-gcc-full-linux-installer-3.2.3.0.run: Syntax error: "(" Unexpected

Even if I double click the.run file from the files directory, nothing happens

i am new to linux and I am doing this for the first time. I have searched the internet but I havent found anything useful.

Please help me in setting up the msp430 gcc tool chain

Thanks
