initdb failure

Hi All

I have been trying to install PostgreSQL-8.4 on Windows 2000 server and
keep getting the following

creating template1 database in
C:/PROGRA~1/CISCOS~1/CSCONccm/objects/PostgreSQL/8.4/data/base/1 ...
initdb: could not execute command
""C:/PROGRA~1/CISCOS~1/CSCONccm/objects/PostgreSQL/8.4/bin/postgres.exe"
--boot -x1 -F ": No error

initdb: removing contents of data directory
"C:/PROGRA~1/CISCOS~1/CSCONccm/objects/PostgreSQL/8.4/data"

I have checked the archives but did not see any solution so far.

The data directory does have inheritable permissions for user postgres
to read, write, modify etc.

Thanks
