Hi Patrick,
Please understand that ManageEngine patch management is not a Microsoft product, of course you could use it for deploy update, but if there is any issue appeared after deployment by this method, it may not be related to Windows system itself.
On the other hand, you could try the command to install language:
Dism /online /Add-Package /PackagePath:C:\test\LangPacks\lp.cab
Detailed information here:
