Hi Johan! First of all, thanks for your reply but I already followed that KB but I am still having the same error. Thanks again. edgee

Hi,Is this a new server you are installing Exchange on ? If so is this a standard install or did you change things ?Also from where are you installing Exchange, are the setup files on hd/dvd, if hd then check the following forum:http://www.tech-archive.net/Archive/Exchange/microsoft.public.exchange.admin/2007-12/msg00143.htmlIf available post theExchangeSetup.log log.Regards,Johan blog: www.johanveldhuis.nl

Dear Edgee, Did you install Exchange server 2003 or 2007 when you encounter the error? Which version is your operation system? What about the SP information? Send the setup log file to v-rocwan@microsoft.com for analyze. For Exchange server 2003, the file name is Exchange Server Setup Progess.log which is located at <drive> root directory. For Exchange server 2007, the file name is Exchange Setup.log which is located at <drive>\ExchangeSetupLogs\ folder. When you send e-mail to me, please let me know the URL of the post.

What roles are you trying to install? ARe you getting this as soon as you launch Setup?What server are you installing on? Have you done Run As Administrator?BP

It happens on my Exchange 2010 mailbox server role installation. The same role was previously installed and later uninstalled due to other errors. I simply clean up the Windows 2008 R2 registry on all Exchange Server entry and the error never comes up and Exchange server installation succeeded.
