Yesterday I have tried to install SQL Management Studio Express on Vista Business x64. But An error code 29506 encountered and installation failed and roll-back.

I have observed that most of apps based on MSI (.msi) encountered in Windows Vista, when UAC enabled. The main problem with MSI files is that you cannot right click it and “Run as Administrator” to bypass UAC validation. To solve this problem, Either you have to logged-in as Default Administrator account or disable UAC.


But don’t worry, There is another way to install SQL Management Studio Express on Windows Vista x64 flawlessly.

How To:

  1. Run CMD as Administrator and Approve the UAC prompt and type the full absolute path of the MSI file, Such as:
  2. C:\>E:\Downloads\SSMS_x64.msi

  3. Follow your screen instruction and be happy with Windows Computing.

Applies To:

  • Windows Vista x64 editions
  • Windows 7 x64 editions

    Worked perfect!

    For those who were a bit dumb like me (… ok very dumb) and took 2 mins to figure it out, fool proof expanded instructions are below.

    1)Move the installer package to the root of your hard disk which windows is installed in (c: for most of us)
    2)Single left and click on the installer
    3)Press “F2” and rename it to “sqlinstaller” or something easy to type (maintaining the file type)
    4)Click on “start” > “All Programs” > “Accessories” > then right hand click on “Command Prompt” and click on “Run as Administrator”
    A window will appear titled “User Account Control”, saying “Do you want to allow the following program to make changes to this computer”
    5)Click “Yes”
    6) Type: “cd\” without the quotes and press enter
    7) Type in the file name you renamed the file to and add .msi to the end and hit enter. (eg “sqlinstaller.msi” without the quotes)
    Then install as per usual.

    Remember to delete the installer off the root of your drive. Its not good to be messy.
