Not enough requirements

I wanted to install Heroes of Might and Magic IV (yea i know, old game) because I found the CD when I was clearing my table and was wondering how come i bought the CD and never ended up playing. Perhaps my earlier system couldn’t support it.

Anyway, so I ran the installation file and got this error (click to see a bigger pic in a new window):

Lol! Apparently 2gb of memory may make my game run sluggishly, become unstable or fail to run at all.
In the end, I couldn’t install it coz it was stuck at 78%. No wonder I didn’t install it the last time
