If you’re installing PowerPivot and you are getting an error when installing PowerPivot on SharePoint that reads http://localhost:32843/SecurityTokenServiceApplication/securitytoken.svc had an innerException and or an incorrect SOAP address.

 

To reset the STS run the following lines:

$sts = Get-SPServiceApplication | ?{$_ -match "Security"}
$sts.Status
$sts.Provision()

$h = Get-SPServiceHostconfig
$h.Provision()
$services = Get-SPServiceApplication
foreach ($service in $services) { $service.provision();
write-host $service.name}

Then run IISRESET
