Based on our communication yesterday, we tested it locally, and the results show that KB2880552 is installed, the version number in central administration is still 4569, not 4571, but the version number in the registry has been updated to 4571.
April CU is checked for the version number before it is installed, and looking at the XML file after extracting the installation package can be found similar to the following conditions:
<targetversion validate= "true" comparisontype= "Equal" comparisonfilter= "Majorminorupdate" >15.0.4571.1502 </TargetVersion>
Follow the script in the SharePoint server below to check the registry.
Check version:
# PowerShell script to display SharePoint products from the registry.
Param (
# decide on whether all the sub-components belonging to the product should being shown as well
[Switch] $ShowComponents
)
# Registry to get info about installed software
$RegLoc = Get-childitem Hklm:\software\microsoft\windows\currentversion\uninstall
# Get SharePoint Products and language packs
Write-host "Products and Language Packs"
Write-host "-------------------------------------------"
$Programs = $RegLoc |
Where-object {$_. Pspath-like "*\office*"} |
foreach {Get-itemproperty $_. Pspath}
$Components = $RegLoc |
Where-object {$_. Pspath-like "*1000-0000000ff1ce}"} |
foreach {Get-itemproperty $_. Pspath}
# output either just the info about products and Language Packs
# or also for sub components
if ($ShowComponents. IsPresent)
{
$Programs | foreach {
$_ | FL DisplayName, DisplayVersion;
$productCodes = $_. ProductCodes;
$Comp = @ () + ($Components |
Where-object {$_. Pschildname-in $productCodes} |
foreach {Get-itemproperty $_. Pspath});
$Comp | Sort-object DisplayName | FT DisplayName, Displayversion-autosize
}
}
Else
{
$Programs | FL DisplayName, DisplayVersion
}
