Local Websphere Express Test server is not present in 5.1.2 insta llation

Hello. I installed WDSC version 5.1.2 on my laptop. I took the installation
options to have the test environment installed locally. I then created a
WebFacing project which I wanted to run on the local test server. When I go
to run it, the server creation window comes up, but the local WebSphere
Express Test Environment server is not present to choose, as it used to be
in versions 5.1 and 5.0. Only WebSphere version 4.0 (not test), versions
4.1, 4.0 and 3.2 of Tomcat and several options under an "Other" folder. The
choices under the "Other" folder do indicate a "WebSphere v5 Express Server
Attach", but this does not seems to be correct unless something has changed.

The only thing that I did differently for this installation was to give my
workspace a non-default directory name. Why do I not see a "websphere"
directory on my C: drive anymore? Only the WDSC directory exists. Can
somebody explain how the test server is supposed to be installed or set up
in this version?

Thanks.
