I am getting error

failed to install the application content files System.NullReferenceException was thrown. Additional exception information: Object reference not set to an instance of an object.

this happens after upgrading the SQL Server from evaluation to enterprise.

Plus the SharePoint Timer Service keeps stopping every time I run the SP_Config Wizard.

Please help. I tried the psconfig

-cmd upgrade -inplace b2b -wait –force 

but it didn't make any difference

If this is a farm with more than one SharePoint-server, run the following command on the failing server:

Get-SPProduct -local

Wait. Wait a little longer, since it takes a while to run. It will reset the patch upgrade cache which sometimes fails. When finished, run the PSConfig.exe script again.

Still in trouble? Open the log-file (stated in the CMD window) and find a more detailed error report.

  • Hi Benny, This is only a single server Farm,should I continue with that command. Nov 25, 2015 at 9:09
  • @Calvin_Klyn Yes. It does no harm to SharePoint. I just wanted to clarify that you need to run the script on the failing server. Good Luck

Remove all comment from your web.config files and rerun the configuration wizard again, it should work. I know this because I've also experienced that issue.
