Installation problem

[autoplant_user]

The install of Core PIW installs under the proper folder structure…
C:\Program Files\Bentley\Plant 2004\P&ID etc.
The install of PID installs under the proper folder structure…
C:\Documents and Settings\All Users\Application Data\Bentley\Plant 2004 etc.

However, on a few machines the PID install is placed on the root of C:\ ...How can I prevent this from happening so it installs in the proper folder structure?
Thanks.

Both the PIW core and P&ID install files under 'program files' and 'doc..s and settings'.
On first installation you can select a network or stand-alone install. the difference is the location of the 'program files' - folders, the 'doc..s and settings' -folders are the same for both.
The 'doc..s and settings'-folder hold user-specific files, the other are 'common'

When installing for the first time, you can select the folders. Even after an un-install you will not be able to re-select them ... unless you clear or change the [HKEY_LOCAL_MACHINE\SOFTWARE\Bentley\Plant85] - keys in your registry.
