Can anyone help with this setup - I run SD on a Macbook Pro with Parallels.



Lately it has been getting hard to get SD to open. I open Parallels, login to Windows 7, double click on the SD alias. I get a little blue circle for a couple of seconds, then nothing. Up to today, i would wait a while (frustrating, I want to go flying!) and then try again. SD would usually open, and i would find I have 2 versions of the programme running. (How is this even possible?)



Today, I can't even get it to open at all.



I've tried downloading v2.2 again, but I can't get W7 to re-install it. Double click on the installer, nothing happens.



I'm somewhat hampered by being unfamiliar with Windows - I got Parallels and W7 solely to run SD.



Can anyone suggest anything please?

Virtualization can be quite a hassle at first. First of all, make sure Your Mac has enough RAM. When You deal with virtualization, the more the RAM, the better the performances. Based on my experience, 4 GB of RAM are the minimum acceptable amount for a good experience.



Next, it is important not to assign too much RAM to the virtual machine, because that RAM is taken away from that available to Your Mac for its needs. A thumb rule would be not to exceed half of the available physical RAM.



Windows 7 requires at least 1.5 GB of RAM to give acceptable performances, 2 GB is the sweet spot for a virtual machine using it, so Your Mac needs at least 4 GB of RAM to be able to decently run a virtual machine with Win7.



I have a self-built PC, running Ubuntu Linux with 4 GB of RAM and a virtual machine with Windows XP using Virtualbox (an Open Source equivalent to Parallels). I assigned 512 MB of RAM to that virtual machine and I'm fine with SkyDemon, as well as many other applications.



Hope this helps.

Filippo
