Problems installing Portal Toolkit plug-in

[emrys emrys]

Sorry for my english 'cause I'm french.
I've got an error message when I try to install the Test environment. I've got the following message: "WebSphere Portal is already installed in another directory" but I can't use the test environment under WSAD 5.0 even if I unintall and reinstall it.
Please HELP ME!!!

I am new to Portal and not familiar with this problem, but I wonder: do already have Portal installed on this machine, apart from the Portal you are trying to unstall in the WSAD test environment?

yes Portal is already installed

I'm under the impression that there are two supported development configurations for portal. First is the remote server, where the portal server is on a separate machine. Second is the local test environment, a local portal installed under the control of the toolkit.
It sounds like you are trying to set up a local test environment on a machine that already has a portal installed. Perhaps the toolkit is refusing to install another portal to avoid conflicts with the portal you have already installed.

As of this writing, this is for Portal 4.2 and 4.2.1.
