some problem when installing postgresql

["Yu Qun" <maggie(dot)qun(at)gmail(dot)com>]

hey:

I am the new one to use PostgreSql, when I install the MoteView including
postgresql and postgresqlODBC and so on, I met a problem about PostgreSql
installation, it shew that "Failed to set permissions on the installed
files. Please see the logfile in "C:\Program Files\PostgreSql\8.0.0-rc
1\tmp\pgperm.log".  in the pgperm.log, it says that "No mapping between
account names and security IDs was done.". I dont know what is problem?
would you like to give me some idea on it? Thanks!

Sincerely;
Maggie
