ConfigMgr 2012 R2 Prerequisites Installation tool – Version 1.2.1 has been released

Today I’ve released the newest version 1.2.1 for my ConfigMgr 2012 R2 Prerequisites Installation tool.
The new features included are:

  • Added validation for checking of current user is a Schema Admin when extending the Schema

  • Hi
    I tried the new version and there seems to be something wrong with the Install ADK Online part.
    It told that it completed the download and installation within a couple of seconds. It turned out to be and internet connection problem.
    Try to disable the nic and you can see for yourself.

    • Hi Sem,
      Hmm, yeah you’re right when I look through that part of the code it doesn’t perform a check if there’s an active internet connection (I’m assuming there is). Will put that on the fix list for new version. Thanks for pointing that out!

      • Well Internet connection is one thing, but it should say that it completed the installation when it didnt 😉
        Also Im trying the install WSUS – WID, but it keeps askin for an SQL Server name

      • I’ve corrected the WSUS WID issue now, made a check against the wrong variable. Updated on the TechNet gallery now!

      • There is an issue with the WSUS SQL installation as well. As I ran the script whatever name I put into the SQL Server field I kept getting “Please enter a SQL Server computer name. Looking at your script code the problem could easily be located:
        if (($TextBoxWSUSSQLServer.Text.Length -eq 0) -or ($RadioButtonSQL.Checked -eq $true)) {
        Write-OutputBox -OutputBoxMessage “Please enter a SQL Server computer name” -Type “ERROR: ”
        The part where is goes wrong is:
        “-or $RadioButtonSQL.Checked -eq $true” which stops the script from continueing. Just replaced it with “-and $RadioButtonSQL.Checked -eq $true” and everything works fine.

      • Hi Thorsten!
        Thanks for letting me know, I’ll update it straight away! Great find 🙂
