Error 85640001 during installation with Win 7


  • Hello everyone,

    I wanna install SQL server 2012 Entreprise edition but I have an issue during the installation. (ISO 4.9Go)

    I'm working on a Win 7 OS, i5, x64, sp1.

    First, I've installed on my computer this edition, any problem. I used Deamon Tool. Then, I tried to install it on my laptop and it doesn't work. After installing rules this error comes up :

    SQL server setup has encoutered the following error:
    There was a failure to calculate the default value of setting INSTANCEID.
    Error code 0x85640001.

    I thought it was a corruption issue, I've re-downloaded the ISO, same problem. I've changed DeamonTool to Winrar, same problem.

    I've downloaded another version of SQL Server (developer this time) and again same error!

    Now, I don't know what can i do =/

    Help me please.

  • Hi Maggie,

    SQl Server 2012 is working on my computer (Windows 7 pro).

    I've downloaded SQL Server 2012 Developer for my laptop which support Windows 7 (my edition is Home Prenium) but I've the same error. I will use a CD this time and I will come back here to tell you if it's working.
