First attempt – it installed the following without a hitch:

• SQL Setup Support Files
• SQL Native Client
• SQL VSS Writer

but then failed miserably on the SQL Server Database Services, checking through the log files showed nothing out of the ordinary. The summary file stated that the install had been a success, though the installer then wanted to report a fail back to Microsoft headquarters.

So time to start digging, fire up Google and find out who else has had a similar problem, quite a few by the looks of it.

My first attempt at a remedy was to use add/remove programs to remove all traces of the botched install. Then use regedit to remove the following keys (if present) /HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Microsoft SQL (xxxx) where (xxx) is anything after SQL..

After a reboot I tried another install – same error message.

After many variations of the above I then looked slightly further afield, at the MSXML6 parser, this is a pre-requisite of SQL Server Express 2005, and I had downloaded it from the Microsoft download page MSXML6.exe Parser and attempted to install it.

It failed stating that the version installed was newer than the version I was attempting to install, but after more headaches etc I looked at the dlls msxml6.dll and msxml6r.dll and noted that they were not newer.
I tried to remove MSXML6 parser using the add/remove programs – it replied that it couldn’t as it wasn’t installed!
But the .dlls could be seen – and they were registered?! So I unregistered them both using regsvr32 /u and tried again to remove the app using add/remove programs. No luck.

I then downloaded Windows Installer Clean Up tool and scrolled down to find the rouge MSXML6.
Highlighted the app – clicked ‘Remove’, then attempted an install of msxml6.exe, it didn’t complain about any previous version (onto a winner?) and installed correctly.
I then, tentatively, tried to install the MS SQL Express 2005 – and after an age it installed fully…

Wahoo… we have a winner.

All I have to do now is write the application… and I am more of a MySQL man myself.

;o)
