Homestyler Desktop Version 5.0 -- need help with opening!

I was able to install it and open it and use it a couple of days ago.  But after closing the program from the initial use, I can't figure out what i'm supposed to click on to open it again.  All I have is an .exe file to click on.  There is no icon on my desktop to click on.  When I click the .exe file, it wants to uninstall and re-install the program.  I had to do that to open it today.

Am I missing something?  Is there supposed to be a designated icon to launch the programOr is this just what happens with the desktop version every time you go to open it?

If someone is able to help, I would greatly appreciate it.

Thanks in advance :)
