Installation Directory issue

JamesKiller · 12th February 2007, 19:39

During the installation, when it comes to the window where the installer will ask users to enter destination folder. Our default is $INSTDIR\$Proudct_Name, the issue comes when users type in such as G:\ProductName (but there is no G: driver on the machine at all) since it is an editable textbox.
Then click on install button, it will say, we can't wrtie the file, balah,balah......

how to control this?

Are you referring on the standard directory page, or a custom page with directory request control?
Because on the standard directory page when you type an invalid drive the install button is disabled at once.

how to add this driver validation on custom page?

You need to validate the destination path into the custom page's leave function, I'd suggest ${DirState}, see nsis manual http://nsis.sourceforge.net/Docs/AppendixE.html#E.1.20

As I mentioned above on custom page's leave function, you get the state of the control. See included examples into Examples\InstallOptions.
