title: MSI generated by WIX doesn't copy executable, copies other files, worked before
body: <p>I've been working with Pandion (an open source XMPP client), which comes with wix scripts to generate installers. </p>
  
  <p>So far, releasing a patch has worked: I run the included batch file, which ran the wix binaries and created an msi.</p>
  
  <p>With the latest update, however, the installer no longer copies the executable (Pandion.exe) to the install directory. All of the other 400+ files are copied correctly.</p>
  
  <p>EDIT: by update, I mean the changes I made, which are limited to a few javascript files. The wix files are all unchanged.</p>
  
  <p>I've been trying to figure out what the problem is, but I'm just not that experienced with wix/msi and don't really know where to look.</p>
  
  <p>I've got verbose logging enabled, which confirms all files are copied except for the executable. The auto-generated component.wxs contains the executable as a component. The installer first registers all components, including the executable, but when it starts copying files it just silently skips it and moves on to the next one.</p>
  
  <p>If I run the installer again and repair the installation, the executable gets copied correctly.</p>
  
  <p>If I uninstall everything and re-install from the first installer, all the previous patches work fine.</p>
