If you followed my last post about not being able to install the Microsoft SQL Server Reporting Services 2005 Print Control, then this post may have the answer for you.
The key is to first get the files that you need to install. You can grab them off the server as they are in one file C:\Program Files\Microsoft SQL Server\MSSQL\Reporting Services\Bin\RSClientPrint.cab.
Crack the cab open (most zip compatible packages should work) and extract all the files. Using your favourite MSI maker, such as Visual Studio 2005 or Wise Package Studio etc, you need to place all of the files into %WINDIR%\Downloaded Program Files and then do a COM Registration of the rsclientprint.dll file.
