problem with installation of Sql server express 2008

  • i already have visual studio 2008 on my laptop. i am trying to install ms Sql server 2008 express but for one reason or another the installation stops .last time it was because master.mdf was already installed on my system. i checked and found out that C:\Program Files (x86) contains both 'Microsoft SQL Server Compact Edition' and 'Microfost Sql Server' folders. How can i install Ms sql server 2008 express? Thanks....

  • You could try installing the software to another, customised location outside of that which you already have.

    Without a more detailed description of your setup it is difficult to offer mre asvice at this moment.

  • If you got the error that master.mdf was already present, that sounds like you have an abandoned instllation with the same instance name as you are trying to use now. Try running install again, using a different instance name.

    The folder for Compact Edition, you can ignore.

  • thanks for the reply...i was able to install Ms sql server 2008 express R2...but it has only Configuration tools but no Management Studio. i downloaded "SQLManagementStudio_x86_ENU.exe" and "SQLManagementStudio_x64_ENU.exe" and tried to install it..

    i chose Installation type as" new installation" but the installation stopped at the Installation Rules stage ..."Previous Release of Microsoft visual Studio 2008 Failed"

    Next, i chose Installation type as" new installation"

    When i choose"Add features" i get an error"Instance ID cannot contain special characters"

    what am i doing wrong?Please help. thanks..

  • It seems that the installation runs into problem because of the broken VS2008 installation. Although, there is no reason to enter an instance ID, since all you are installing is the tools. But I don't know the exact screens that SQLManagementStudio_x64/86_ENU.exe displays, and I cannot easily test it.

    But maybe you could try with installing SSMS 2012 instead? You can use it with SQL Server 2008 R2 without problem, and personally I find it somewhat nicer to work with.

  • Firstly I would suggest deinstalling anything SQL Server and anything Visual Studio. It is clear from your post that you have somehow failures in both Software packages. Delete the Installation Folders from the file System and any registry entries and then try again.

    MAKE SURE YOU BACK EVERYTHING UP FIRST!!!

    When you start from this Position you should have no Problems.

    You should however be careful when naming your instance because there are illegal characters that obviously can't be used. Stick to alphanumeric naming conventions with an underscore (_) if necessary.

    The installer mentioned that the master database is already present and that the instance Name contains illegal characters so I doubt the Problem is only with the Visual Studio Installation.

    Your Suggestion of using SSMS 2012 should also be treated with caution. Although I haven't used it myself, I have had Problems administering SQL Server 2005 instances with SSMS 2008R2. I prefer if at all possible to use the appropriate SSMS for the database Version.

  • i came across this . can u kindly verify this

    "SQLManagementStudio_x64_ENU.exe is NOT SSMS! Confusing filename, huh? It includes only the basic management tools (e.g., Configuration Manager) and support for SSMS. To install SSMS itself you need SQLEXPRWT_x64_ENU.exe. (No need to download SQLManagementStudio_x64_ENU.exe) "

    The only way I could verify or falsify anything is to download and install myself on a fresh VM. I will not have the time to that today. Someone else who can help?
