Just to clarify.
The hotfix was put into f:\softrak\upgrades.
When the file was double clicked on - run, loading Adagio, welcome screen, proceed, downloading file. May take several seconds, click install -
this is where the problem came in -
could not communicate with network server error 1.
When abort was clicked - - file c:\documents and settings\fowler\local settings\temp\TmpSsi\oehsp20101222Etc.zip could not be open.

This was tried on another workstation with the same results.
