windows magic (not?)

[Jack]

I'm away from home, with my Windows laptop, and I want to check 
something in my kmy file, which I have a copy of.  I downloaded the 
windows installer from the link on the home page and ran it. I have now 
clicked on the icon; I have tried to launch from cmd; I have tried to 
launch from ConEmu; I have tried to launch from a Cygwin shell - all 
multiple times.  In a few cases, I think I may have seen some window 
flash briefly on the screen.  Other than that I have nothing.  No 
windows, no evidence of files created.

Am I missing something?  I really didn't think there was anything magic 
about this.  I've done it in the past, but not recently.  I have checked 
that there are no remnants of an old install anywhere I can find.

The laptop is an HP Compaq Presario, running an updated Windows 7 
Professional.

Thanks for any suggestions.
