Installshield problem

[nflutter]

I've been trying to install a program without success, the problem seems to be with the msi installer. I have downloaded the latest isscript11.msi installer but when i try to run it i get a 'windows cannot open this file. Windows needs to know what program created it...... blah blah!" basically my system is not recognising a .msi file. Obviously something has happened here, maybe some corruption or dare i say it something i have done in error!! Can anyone help or point me in the right direction. Beginner level answers please, only a novice trying to keep my own office network running!!
Thanks in advance.

with a little googling i think that maybe i need to download and install the instmsi.exe file but i cant find a version that is specifically for SBS2003, any help here! Is it the same file name for SBS or is the file called something else? Thanks
