Prerequisites Error on KB976462

Mar 25, 2011 at 8:11 PM

The first time I run the AutoSPInstaller (I'm using online mode) it gives a warning that KB976462 could not be installed (full details below). So I tried to install it manually and it said that the hotfix is not applicable. If I then run AutoSPInstaller again, the prerequisites install process completes just fine and it goes on its merry way. Anyone know how to work around this?

Are you running Win2008 R2 SP1 on the target server? I have been getting this too, after I upgraded to SP1. Odd, but yes it just involves running the script again and everything goes seemingly fine.

Yes, I am using Windows Server 2008 R2 with SP1. If anyone has any suggestions for a fix or workaround that doesn't involve running the script twice it would be much appreciated. I am about to start testing configurations for building a 4 server farm.

Hi all,

The same behavior here. I'm also on Server 2008 R2 SP1 and I'm wondering if there is a fix or a workaround that doesn't involve running the script twice as I'm trying to automate as much as possible!

I had the same error.  Ran the launcher a second time, and same again.  Did a Windows Update and reboot.  No more problems

Note I've had this happen without using the scripts, by just running the spfoundation downloadable on a 2008 R2 SP1 clean box.  Google is showing others having the same issue.  A rerun of the spfoundation install fixed it (actually skipped it) as well so this isn't related to autospinstaller IMO, but a current prereq bug for 2008 R2 SP1 boxes.

Hey all, the next AutoSPInstaller release will automatically just re-run the PreRequisiteInstaller if it encounters this error. Hopefully this bug will be fixed for good in SharePoint 2010 SP1.

FYI everyone - MS actually describes a workaround for this, which will be put in place in the next drop of AutoSPInstaller (to replace the current workaround):


It simply involves installing the .Net Framework Windows feature prior to running PrerequisiteInstaller.exe...!
