I get the error that "setup can not continue with the upgrade because the (exchange server 2007 sp1 setup) process id xxxx has open files close the process and restart setup" This is a running Exchange installation. the process id for the above mentioned process is the sp1 install, so killing that process also stops the install, and yes rebooting and trying again re downloading and basicly any running of the install results in the install failing because the install is running (very obvious joke here some place). I am running on 2003 x64 and the sp1 is also x64. Please save a bald man from pulling his eyebrows out.

Dear customer: In order to better troubleshoot the issue, please help collect the following information. Did you perform clean Exchange server 2007 SP1 installation or upgrade current Exchange 2007 RTM to SP1? Send the screenshot of the error to v-rocwan@microsoft.com for analyze. On Exchange server, navigate to <system drive>\ExchangeSetupLogs\ folder; send the ExchangeSetup.log file to me. Where did you download the Exchange server 2007 SP1 package? Try to download Exchange Server 2007 Service Pack 1 from the following link, and try to install Exchange server 2007 SP1 again, check the effect.
