I have Windows 7 OS and I have downloaded SVN INstaller from the link you gave.To be more specific from:
I get an error when I try both the Installation packages there.
The ERROR is LIKE:
INSTALLATION PACKAGE COULD NOT BE OPENED.
CONTACT APPLICATION VENDOR TO VERIFY THAT IT IS A VALID INSTALLATION PACKAE..
PLease let me know how to resolve this error as I could see only 2 download links on that page.
