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

<package

 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 /q /x{AC94622D-D899-44DF-9857-7DD31958C541}' />
