Exchange Server 2007 SP3 update fail :- The system cannot find the file specified

Dodgy download I would suspect.
Download SP3 fresh and extract on the server itself, not elsewhere and then moving the extracted files across.

Simon.

Thanks Simon,

I have downloaded again and extracted to a different drive on the server and still the same issue.

It is when it gets to the 'Mailbox Role' stage:

Error:
The system cannot find the file specified
11 times

Have you rebooted the server and tried the update again?
What else is on the machine?
The prerequisite check doesn't throw any warnings at all?

Simon.

Hi Simon,

I have rebooted several times,
This is the 6th attempt.

The prerequisite check runs fine.
There is nothing out off the ordinary on the server,
Just Standard SBS 2008.
All updates are applied too

There must be something else in the log file to indicate what file is missing - the log snippet you have posted doesn't say which file it is.

Simon.

Thanks Simon,

Here is the latest failure log:

Are you upgrading from SP1 or SP2?  If you skipped SP2 be sure to run the Exchange setup.exe with /preparead switch to update your AD schema.

Jeff

You shouldn't need to run prep manually, the setup wizard will do it for you.
I only run prep manually in multiple domain forests or where the schema master is in a separate site from the Exchange server.

Simon.

If you don't run it manually on an SBS it can cause some services to stop and not restart.

I still cannot get 2007SP3 to install.
If I run the SBS 2011 Migration Preparation Tool it says

The Scan detected 1 errors and 0 warnings:

'Microsoft Exchange Server 2007 SP3 not installed'


Doe anyone have any ideas?

Same problem:

11x ErrorRecord: The system cannot find the file specified

"There is nothing out off the ordinary on the server,"

That doesn't really answer the question on what else is on the server.
Instinct says interference. What else, apart from the base SBS product, is installed on the server?

Simon.

Thanks Simon,

Sophos Antivirus
Symantec Backup Exec

Does the AV software have the correct exclusions in it?
Although personally I would remove it, reboot the server and then attempt the installation again.

Simon.

Hi Simon,

I have removed Backup Exec, Sophos AV and all other non MS software from the server rebooted and ran the update and still the same issue:
