Last year I tried to install TOPO! (mapping software...) on my computer, but couldn't.
I put is on my wife's computer and it runs fine.
I just bought a new computer and tried again. It still won't install.
It says I am missing Installscript Engine, and need isscript.msi.

Any downside to installing it? Safe and all that stuff.

Only thing I found about installing it is from 2010, but that is likely to be obsolete.

Thanks much.
