I'm currently on BES 4.0.5.6, which I upgraded from my original installation disks of version 4.0.

The BES server is on a Windows 2003 server with Exchange manager installed.

The SQL Server is SQL 2000 sitting on a remote server.

Stepping through the BES 4.1 SP4 install and during the database upgrade, it stops the BES Services and then fails to do the db upgrade with the message

"DB upgrade failed. Unable to open a required file"

I've tried with both Windows authentication and SQL Authentication. I'm logged on as BESAdmin to do the installation (fairly certain that's what i used for the original install and upgrade).

Any ideas?

The prerequisites only fail on Java 5.0 update 11 (I have version 6 installed so ignored the error).

hmmm, the setup log seems to suggest it fails on creating the following file;

which is strange, because just a few steps earlier it created (or copied) a script for the backup of the DB in exactly the same folder i.e.

I would recommend uninstalling all old versions of java, and only have the java 5.0 update 11 installed. Then resetart your server and try upgrading again.

done, got rid of my final prerequisite, but still same problem :(

hmmm, stranger and stranger ...

i've use filemon to see the opening and closing of all files and it shows the setup.exe creating the file but it gives a bad filename

from the image below, you can see that there's an odd character in the file name.

surely i can't be the only person experiencing this issue. i've tried re-downloading the installation again but it hasn't helped.


i got my install files from ftp://ftp2.rim.net/, is there anywhere else to get them from?

solution just in case anyone googles this and has the same problem.

for whatever reason the download from the RIM ftp i was given appeared to be corrupt even after downloading it a couple of times from different locations.

i finally got an installation CD direct from my carrier and it installed without a hitch.
