Step 3

Navigate to:

For 64 bit OS

C:\Program Files (x86)\Lenovo\System Update\session\system\SSClientCommon

Open file MappingInterface.xml using Notepad

Add the following lines:

<OS>

<OSTVIA>WIN7-PRO.SP1</OSTVIA>

<OSeGatherer>

<Name>Windows 7 Professional</Name>

<ServiceRelease>Service Pack 1</ServiceRelease>

</OSeGatherer>

<OSPCDPackSpec>7.SP1</OSPCDPackSpec>

<OSQuest>Windows 7</OSQuest>

</OS>

If you're using other version than Professional, just change WIN7-PRO.SP1 to WIN7-UTL.SP1 etc and 4th line to WINDOWS 7 Ultimate.

You should be able to run the System Update now.

This fix can work for any other Windows Operating systems as long as correct name and version is put into the above code.

For Windows Server 2008, try the following code, I've put together. Bare in mind that it is not tested so please take a back up of the original XML file stated above before making changes on the server.

<OS>

 <OSTVIA>WINSERVER2008-Standard.SP1</OSTVIA>

 <OSeGatherer>

 <Name>Windows Server 2008 Standard</Name>

 <ServiceRelease>Service Pack 1</ServiceRelease>

 </OSeGatherer>

 <OSPCDPackSpec>2008.SP1</OSPCDPackSpec>

 <OSQuest>Windows Server 2008</OSQuest>

</OS>
