Thanks to some off list help from Levi Wilson, I now have the following
solution...
<?xml version='1.0' encoding='windows-1252'?>
<Wix xmlns='http://schemas.microsoft.com/wix/2003/01/wi'>
<Fragment Id='PdfFragment'>
<Property Id="PDFFOLDEREXISTS">
<DirectorySearch Id="PdfFolderSearch" Path="[SourceDir]pdf\" />
</Property>
<CustomAction Id='SetPdfFolder' Property='SourcePdfDir'
Value='[SourceDir]pdf\'/>
<DirectoryRef Id='PdfFolder'>
<Component Id='PdfComponent' Guid='1DC5A176-1062-4b7d-A2B3-DCD15EE050A9'>
<Condition>PDFFOLDEREXISTS</Condition>
<CopyFile Id='PdfFiles' DestinationDirectory='PdfFolder'
SourceProperty='SourcePdfDir' SourceName='*.pdf'/>
<Shortcut Id="StartMenuPdfFolder" Directory="ProgramMenuDir" Name="PDF"
LongName="Training Material" WorkingDirectory='PdfFolder'/>
</Component>
</DirectoryRef>
</Fragment>
</Wix>

Subject: Conditional installation of a shortcut based on a folders existance
Conditional installation of a shortcut based on a folders existence
Hi all,
I'm tying to create an installer that copies some files from the installation
media (if they exist) to a location on the target machine. I'm then trying to
add a start menu entry that points to this location so far I have this fragment
that does most of the work...
<?xml version='1.0' encoding='windows-1252'?>
<Wix xmlns='http://schemas.microsoft.com/wix/2003/01/wi'>
<Fragment Id='PdfFragment'>
<CustomAction Id='SetPdfFolder' Property='SourcePdfDir'
Value='[SourceDir]pdf\'/>
<DirectoryRef Id='PdfFolder'>
<Component Id='PdfComponent' Guid='1DC5A176-1062-4b7d-A2B3-DCD15EE050A9'>
<CopyFile Id='PdfFiles' DestinationDirectory='PdfFolder'
SourceProperty='SourcePdfDir' SourceName='*.pdf'/>
<Shortcut Id="StartMenuPdfFolder" Directory="ProgramMenuDir" Name="PDF"
LongName="Training Material" WorkingDirectory='PdfFolder'/>
</Component>
</DirectoryRef>
</Fragment>
</Wix>
The custom action is executed from the InstallExecuteSequence.
This all works fine when the pdf folder exists on the install CD but when it
doesn't I still get the start menu shortcut but it doesn't point to anything.
So I think that I need to make the component conditional. Which I think means
that I need to write another custom action that detects is a folder exists on
the CD and sets a property, but I don't know how to do this. Can somebody help
me?
Cheers
Colin
