uninstall/install internal error 2503 and 2502

i've had this error since i tried re installing steam, and have been searching everywhere for how to fix it and still everything i try doesnt work, anyone know how to fix this

hi,

have you tried to install the program with Administrator Privileges and in Windows XP compatibility mode?

i don't know what windows XP compatibility mode is and when i try to go to c/windows/installer it gives me a dialog box that says it is not accessible and access denied

Sounds like a permissions issue to me.

run as administrator the program

Run as Administrator or Elevated Admin rights = Right Click on .EXE file (install file) and a small window will open, you will then see an option that says "Run as Administrator"... you now left click on this option.

i've already tried to run as administrator... one of the first things i did. still nothing is helping

try to run the program in windows xp compatibility mode.

guide: Compatibility Mode

just tried that it did not work either

Have you gone to the Steam Forums or Tech support to see if they can lend a hand or shed some light?
