Quickbooks Pro 2006 has been very Quick at sucking up 6 hours of my time trying to do installs. Repeated errors over AnswerWorks 4.0 , dll files missing, on top of that I seen a number of interesting things.
Quickbooks Pro 2006 is suppose to be a complete rewrite or at lest a large update, though to me that just appears to be a marketing thing. Perhaps it is just the USA version that is a rewrite as Quickbooks Pro 2006 looks like a rehash of the older version. Two things that I noticed,
1. Install scripts referring to 2003 Quickbooks.
2. The large amount of problems with people installing Quickbooks on XP and yet Windows 98,Me,2000 all seam to go much smother then Quickbooks on XP.
This is based on me testing installs on various machines around to see how things work out. Xp is the only one that seams to have some serious issues.
Which is very silly considering XP is about to be replaced, so my guess is that once Vista is up and running XP will be fine, then some where in 2007 to 2008 they will drop windows 98,Me,2000 support so it handles the Xp / Vistia Kernal much better.
