Sorry you are still having trouble.   Delete my plugins from your Extensions folder if they are giving errors and you need to keep working.

If you extract the Carrara 6 versions into Carrara 5 you will get an "Extension X is too recent" error.  Put the C5 versions in C6 and you get an "extension X is too old" error.

The plugins will work for Carrara 6 Pro, regular or Express editions etc, there is no difference.

Make sure you have the latest 6.03 update for Carrara.  When I first tested my plugins in C6 they didnt show up.  A few reboots and reruns later they did - which was a bit mysterious.  If you have more than one of my plugins they will turn up in a Sparrowhawke3D sub-menu but if you only have one then they might not show up.

Check the compatiblity settings for the Carrara 6 application.  From the little I've seen of Vista it does have better backwards compatibility than XP.

However if Carrara 6 is working perfectly in Vista 64 and my plugins dont then it could be that I've got a compiler setting wrong for 64 bit compatibility.  I base the projects on the ones straight from the Carrara SDK though.**

I finally got it installed, there is now a sub folder for Sparrowhawke, I placed the "Wheels and Track" plug-ins into the folder. I used the "wheels" plug-in and I am using the Humvee that you mentioned in the instructions and I am having a problem getting the wheels to spin following the instructions that you gave for that particular model, I noticed that some of the boxes were'nt checked, such as the one for "enable steering". What actually makes the wheels spin?
