You can either upgrade to the 11.04 Operations Agent which will have this fix included, or otherwise make sure the file is not in use while distribution is taking place. For the dbspiregedit.exe file this can be done by temporarily stopping DBSPI monitoring through the following command:
# dbspicol OFF
After the distribution it can be enabled again:
# dbspicol ON
