In this tread i see "Mike Lagase comment". Where`s true ? Is it safe ? No another ideas ? http://social.technet.microsoft.com/Forums/en-US/exchangesvrdeploy/thread/3d935eb2-b57f-4778-ab49-99e0be0ae2b8 "Please stop deleting watermark keys in the registry to work around these issues. These watermark keys are there for a reason and the actual underlying problem needs to be resolved before continuing setup by using Add/Remove programs. You have to look at the Exchange setup logs to determine what failed by referencing the watermark key in the registry with what is in the setup logs. Deleting a watermark key will leave your server in an incomplete Exchange configuration and YOU WILL HAVE PROBLEMS with your server. You may think that things are installed properly, but somewhere down the road, more problems may occur. There are special considerations for upgrading a CMS for SP1 in which this fails and how to work around it, but for regular non-CMS roles, this is not the way to go. If you cannot figure this out, then you need to call Microsoft support for further assistance. Mike Lagase Microsoft Exchange Escalation Services"

Hi Sergey, So is there any error message in the ExchangeSetup.log ? As I know, the workaround is to delete the Watermark & Action (Please backup the registry first).
