Changes in MUI_PAGE_DIRECTORY

Hi All,

When the space in install location selected by user is less than the space required for installation than the install wizard window will not show the next button, I also want to display error message to user in abouve scenarion. How can i do that?

I think that you should use .onVerifyInstDir function and this wiki page: http://nsis.sourceforge.net/CheckSpaceFree

Thanks Pospec for your reply. But what i want is, instead for disabling that next button i want to make it enable every time even if the disk space is not there and once user click the next button i want to do the validation for disk space.
