[postgis-users] PostGIS install

Hi all,

After the successful installation of PostgreSQL 9.0
(postgresql-9.0.1-1-windows_x64.exe  which has* no Spatial Extensions*) on
Windows 7 ,  I execute postgis-pg90-setup-1.5.2-3.exe without success. The
error message says:
Files/PostgreSQL/9.0/share/contrib/postgis-1.5/postgis.sql:58: ERROR:  could
not load library "C:/Program Files/PostgreSQL/9.0/lib/postgis-1.5.dll": %1
is not a valid Win32 application."
I then checked the missing file (postgis-1.5.dll) which was there.

Could anyone of you tell me how to solve it?

Thank you very much.
