hi guys,
 am a new user to pgadmin3. so i dont have idea about pgadmin fully. i need to install pgadmin3 1.8.4. am using Windows Vista. i've got some installation steps from web search. but it doesn't help. as per the instructions i've downloaded Wix-3.0.2420.0,wxMSW-2.8.8,libxml2-2.6.32, libxslt-1.1.23, iconv-1.9.2 & visual studio 2005. i couldn't download pgadmin3 from pgadmin.com, so i downloaded pgadmin3-1.8.4.tar from http://gd.tuwien.ac.at/opsys/linux/gentoo/distfiles/?fisel=pP. after unzip, i've got so many folders & files. i dont know which one am suppose to use. i tried to build installer under the folder \pgadmin3-1.8.4\pkg\win32. but am getting resource missing error.
 is there any option to get a exe file to setup pgadmin? i dont have the postgresql in my personal computer. i want to access the remote system postgresql. could you please guide me to install pgadmin on windows vista. help me. am looking forward your reply.
