Thank you for the fine tool! I tried a latest version and could not integrated updates to windows 7 installation. It failed with a strange error in LOG: 2009-12-01 22:22:54, Error DISM DISM Manager: PID=2068 Failed to create unique image session lock name for DISM located at 'F:\Install\Windows7\Tools\7Customizer\work\mount\Windows\System32\Dism\dismprov.dll'. - CDISMManager::CheckSessionAndLock(hr:0x801f0005) This tool worked for me in past (previous versions) (Sorry, I can't remeber which version number was ok). But after upgrading to the latest version it failed to integrate. I'm using a clean MSD version of Windows 7 Ultimate to integrate updates to. I've uploaded a LOG file just in case. http://rapidshare.com/files/314783465/dism.rar.html
