stacking software compatible with Windows 7

Hi all. My trusty Windows XP computer finally bit the dust a week or two ago, and I bought a new 64 bit Windows 7 Sony laptop. I had Registar, Registax and a couple of other pieces of software on the old PC that I am finding out will not run on the Win 7 unit (won't even load). What are your (most economical) suggestions on "need to have" software to do DSLR imaging on this thing? I was able to get Nebulosity 2.2.1 to load, but have not tried to hook a camera up to it yet.

Ouch!!! Long live XP!

I suggest Deep Sky Stacker. It's free and has worked well for me, though I haven't tried it on 7 yet.

Have you tried "Run as Administrator". I have found it solves all kinds of issues.
Also, I sometimes have have to do it installs.
