[wix-users] How to ignore invalid/unavailable drive for an optional file/component?

[Kerem]

Hello Jacob,
Thank you for your response. I did add a Condition that checks for
availability of that folder, but the only thing I achieved with it was that
the error message was more user friendly. The installation still failed
immediately when the dialog is closed.

Detecting and assigning properties during install time indeed sounds a bit
hard to manage.

I followed your recommendation and installed the file to the install
directory (that's what you mean by "locally", right?) and then copied it to
user home with a Custom Action. I couldn't get <CopyFile> working with it,
so I used <ExeCommand>.

<Product ...>
  <Package .../>
  <CustomAction Id='CopyFileCA' Execute='deferred' Return='ignore'
Directory='INSTALLDIR' ExeCommand='cmd /c "copy <filename>
[%HOMEDRIVE][%HOMEPATH]"' />
...
  <InstallExecuteSequence>
    <Custom Action='CopyFileCA' Before='InstallFinalize'>
      NOT Installed
    </Custom>
    <Custom Action='RemoveFileCA' Before='InstallFinalize'>
      Installed AND NOT UPGRADINGPRODUCTCODE
    </Custom>
  </InstallExecuteSequence>
</Product>

This solves my problem. But since it does it silently AND I am new to WiX,
I wonder if this can be done in a more "elegant" way. Or is this as good as
it gets in my situation?

Thank you for your support Jacob!

Best regards,
Kerem Ispirli
