SQL Server 2008 Install – MediaInfo.xml missing

I was installing SQL Server 2008 today (x64 bit version) and after the initial checks it does, I got an error about MediaInfo.xml file missing. Looking in the folder where it had unpacked the files, effectively I couldn’t find a reference to it. After a very hard session of extensive research, I found that others had run into similar issues. Some of the suggested solutions were to re-install .NET 3.5 SP1. Others said to re-install the complete .NET framework. One guy had re-installed his entire OS and still had issues.

Clearly not being the path I wanted to go down, I decided to try and install the 32 bit version to see if it was a problem with the 64 bit. This one seemed to go ahead with the install. Looking at the decompressed files, I saw that the missing files were there on the 32 bit. I then cancelled the install and ran the 64 bit one again. After decompressing the files, the missing files were also there. I thought maybe I had a bad run and let it continue. However once it did all the checks and I hit Continue, suddenly half of the files were deleted from the folder. So it seems that at some point the installer was deleting the files.

So instead of running the installer bootstrap, I decompressed the files and ran the setup manually. And it worked. So if you get a errors on missing files, decompress the package and run the setup.exe manually and it should work ok.

    This usually only happens because you closed the “SQL Server Installation Center” dialog. Closing that dialog causes temporary files to be deleted (such as MediaInfo.xml), and causes this error. I was experiencing this problem and found that leaving that first menu open fixes this problem.

    It works, decompress sql-setup such as 7zip and install start setup.exe …
    Why the installer is deleting files, Microsoft know it 😀

    Please dont close your Installation Center throughout the process of SQL Server setup. In this way you would not encounter this issue. Enjy..
