Very excellant post prathapml, I recently installed Office 2007 on my machine and noticed that MSOCache folder is being created under my %HOMEDRIVE%. I went through ORK 2007 documentation and it suggestes that that location should be %PFiles%\Microsoft Office\Office 12\MSOCache. prathapml, can I specify the LIS Location in config.xml in a such way, whenever setup will start cache it will cache only under dir mentioned in config.xml. The config.xml file you have provided is very useful. However, I tried several ways to prevent Access and Visio installation using config.xml. Though I successed the same using .MSP I would like to do the same using config.xml. Can you please give me some tips on this? Thanks a lot.
