Are you sure there isn't some kind of rights issue? The error you're getting means that the installer can't actually see the file MERCURY.EXE in that directory.

Cheers!

hi, i hope it could be simple as usual, just install it OVER the previous version.
any particular hint other than "do a backup first"?

 thanks, Marco
 

That's what I do.  The installer detects the previous version and offers to do an upgrade in that location.

You only need to do a backup of the server directory. All local mailboxes are untouched.

Something has gone wrong here:

I am trying to do an in-place upgrade on my Server 2003 box.

I

have been running M32 for 8 years now, so I should be an old hand at

this. My existing installation of M/32 4.01b is at C:\MERCURY

I

have backed up the folder to CD and run the installer and select the

upgrade option and accept the offer to upgrade to the C:\MERCURY folder.

It then refuses to go any futher as it finds no copy of Mercury/32 there. It is definately there.

 Any ideas?

I have downloaded the installer twice now:

My MD5 checksum is  d661a5e72157f9e8a121824f22b10eaa *m32-451.exe

Many thanks
