Like the error message suggests, your Shockwave installation can't find
"swadcmpr.x32" - perhaps the auto-download checkbox wasn't ticked when
the file was published, or perhaps the auto-download URL fails to locate
the xtra, or perhaps this xtra isn't included in the "full" installer,
FWIW: my installation of SW11 has a copy at 'C:\Documents and
Settings\<username>\Application Data\Adobe\Shockwave Player
Can you provide a URL to the file that fails?
