This is how it was explained to the users at the user conference: AC 3.x is written in visual basic and the database uses Access. In the new AC 4.x the database is run through SQL server and the client runs on a .Net platform. I am not an developer nor am I for sure about the particulars of the programing platform.

I do know that AC 4.x does not work in WINE on ubuntu 8.10 since the .Net will not install or work properly, that is where it hangs up. I tried installing the .Net manually in WINE which does complete the install but the AC will not load because of missing libraries (probably native to Windows). I have not spent a lot of time on this. I am only assuming that since .Net is poorly supported in WINE (and Crossover) that AC 4.x will not work. I am not using the 3.x but from other postings it appears that some people have been able to make the AC work in Linux.

The point that I tried to make in my post was that there is a big difference in how AC 3.x works and 4.x. While AC 3.x can be made to work in Linux (some have reported success) the situation is different in AC 4.x. Reviewing the posts in the forum refer mostly to 3.x.

If someone has been able to get AC 4.x client to work on Linux, I would love to know how to do it. That would enable me to use my netbooks to run AC which are great little computers for simple tasks like vital signs, etc.
