This can be done just with the Windows Installer tables. You need not use any WiX-specific custom actions. To append the backslash, you can use a Formatted string that consists of a reference to the property and the backslash. And to check whether the backslash is there already, you can use a Condition. Formatted: http://msdn2.microsoft.com/library/aa368609.aspx Conditional Statement Syntax: http://msdn2.microsoft.com/library/aa368012.aspx ">> TRUE if left string ends with the right string." If you want to append the backslash when the user clicks a PushButton in one of your dialog boxes, you can put this inside the Control element: <Publish Property="MAXIMIZERDIR" Value="[MAXIMIZERDIR]\" ><![CDATA[NOT (MAXIMIZERDIR >> "\")]]></Publish> If you instead want to append the backslash during an execution sequence, so that it happens even in a silent installation, you must do it in two parts: first define a custom action that actually appends the backslash, and then refer to it from within a sequence table, with a suitable condition. <CustomAction Id="AppendBackslashToMAXIMIZERDIR" Property="MAXIMIZERDIR" Value="[MAXIMIZERDIR]\"/> <Custom Action="AppendBackslashToMAXIMIZERDIR" After="whatever" ><![CDATA[NOT (MAXIMIZERDIR >> "\")]]></Custom> ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
