Just a little something that occasionally affects those that have Windows Vista/Windows 7 onwards.
During the CADSTAR installation you are prompted for the paths to install to, this is split into two paths - Program and User files.
Program files go into: C:\Program Files\Zuken\Cadstar13.0\Program
User files by default go into Public\Zuken\Cadstar13\.....
Later on when trying to find files the user - perhaps having recently upgraded from Windows XP cannot find half of the installed files - where is this elusive public folder and what is the point of it?
While I know where it it and it is supposed to be for sharing your files it is generally better to put your shared files on a network shared drive etc.
So during the install I ALWAYS copy the path for the program files to the user files path before continuing.
Saves a lot of hassle, confusion and head scratching.
Anyway - that is what I and a lot of others do -it is up to you what you do.
Update: As an update to this I want to mention that sometimes (Especially with Windows 7) Microsoft consider us all incompetent and do not allow us to write to files within the Program Files folder, this is why a lot of stuff gets put in public. So if you do as I have advised then you may also need to take ownership of the Zuken folder and all subfolders below it. (Mr Google can tell you how).
