the process explorer was the big help for me. what i did while the installation was running was open up process explorer saw what it was running and obviously figured out what it was trying to do and i just went and manually did it myself then i'd kill the icalc.exe...after that another one popped up and i did it again the first time was for the user i was logged in as...the second was for the postgres user...after i set the permissions manually i killed the other icalcs.exe and then it continued to initdb... hope this helps -- View this message in context: http://postgresql.1045698.n5.nabble.com/Problem-with-the-9-1-one-click-installer-Windows7-64bit-tp4794537p4845892.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
