Since SCCM 2007 Software Package runs as a 32-Bit proces I ran "reg export" to export the "KLM\SOFTWARE\WOW6432Node\Microsoft\SMS\Mobile Client\Software Distribution\Execution History\System\" registry keys into file and then ran "%windir%\sysnative\reg import" to import this information under "HKLM\SOFTWARE\Microsoft\SMS\Mobile Client\Software Distribution\Execution History\System\ After that the Software was not redeployed when updating the sccm Agent on a Windows 7 x64 Client.
