Error installing plugin: "Resulting configuration does not contain the platform."   

Hi,
I follow instructions and install via local update site. Last dialog says,"Select features to install:". When I select the "rsa-scxml-plugin" feature, I get error message, "Resulting configuration does not contain the platform."

At this point, the Finish button is disabled and I am unable to install the plugin.

Then I unzip into RSA's feature and plugin dirs. When I restart and config the transformation, SCXML does not appear in the list of transformations.

I am using RSA 7.0.0.3 on Windowx XP, 2 GB memory.

Any suggestions?

Thanks, y
