Crystal Reports

This is a silent installer and uninstaller for Crystal Reports (and, a language pack).

   <package
       id="crystalreports"
       name="Crystal Reports"
       revision="1"
       priority="0">
       <check type="uninstall" condition="exists" path="Crystal Reports for .NET Framework 2.0 (x86)" />

       <install cmd='msiexec /i "%SOFTWARE%\CrystalReports\CRRedist2005_x86.msi" /q ALLUSERS=1' />

       <remove  cmd='MsiExec.exe /q /x{7C05EEDD-E565-4E2B-ADE4-0C784C17311C}' />

   </package>

Language pack - if you have a different language version, you'll have to make adjustments to uninstall string, and to remove cmd:

   <package
       id="crystalreportsLP"
       name="Crystal Reports language pack"
       revision="1"
       priority="0">
       <check type="uninstall" condition="exists" path="Crystal Reports for .NET Framework 2.0 Language Pack (x86) - DEU" />

       <install cmd='msiexec /i "%SOFTWARE%\CrystalReports\CRRedist2005_x86_de.msi" /q ALLUSERS=1' />

       <remove  cmd='MsiExec.exe /I{AC94622D-D899-44DF-9857-7DD31958C541}' />

   </package>
