[wix-users] Prevent installing to a directory with demo in the name

[KONDURU Pavan]

Hi Jonathan,

As far as I know you can't achieve this without a custom action. This is what you need:

--Set up a property that is public(All uppercase). Something like say " VALID_INSTDIR" with value="YES"

--Define a CustomAction and Link that to the next button of the Install directory dialog(make sure the CA is immediate)

        <Control Id="Next" Type="PushButton" X="248" Y="243" Width="56" Height="17" Default="yes" Text="!(loc.WixUINext)">
                    <Publish Event="DoAction" Value="ValidateDir">1</Publish>

--Write a c# or C++ CA and check for the string "Demo", something like this in C#. Change the VALID_INSTDIR value to "NO" if it contains demo.

        string instLoc = session["INSTALLLOCATION"];
                 if (instLoc.Contains("Demo"))
        session["INSTDIR_VALID"] = "NO";

-- --So, now you have a property which can decide if you want the user to proceed . You can use this in the UI sequence

--Write a custom dialog to be called when its invalid with appropriate text to warn the user and stay on the install directory dialog.

Thanks Farrukh,

I found this guide:
http://wixtoolset.org/documentation/manual/v3/wixui/wixui_customizations.html

in the section "Changing the UI sequence of a built-in dialog set" it shows an approach to modifying the Next button behavior of InstallDirDlg.

I tried changing:
<Publish Dialog="InstallDirDlg" Control="Next" Event="SpawnDialog"
Value="InvalidDirDlg" Order="3"><![CDATA[NOT WIXUI_DONTVALIDATEPATH AND WIXUI_INSTALLDIR_VALID<>"1"]]></Publish>
to
<Publish Dialog="InstallDirDlg" Control="Next" Event="SpawnDialog"
Value="InvalidDirDlg" Order="3"><![CDATA[NOT WIXUI_DONTVALIDATEPATH AND (WIXUI_INSTALLDIR_VALID<>"1" OR WIXUI_INSTALLDIR="C:\DEMO\")]]></Publish>

I also tried:
WIXUI_INSTALLDIR="DEMO"

However, I was still able to install to C:\DEMO\

I would like to prohibit installing to any folder named DEMO:
C:\DEMO\
D:\DEMO\
E:\Program Files\DEMO\
etc...

Thanks again for your first reply. Do you have any more guidance? I'm not sure how/what I should check for the contents "DEMO"
