After I realized that this language pack was 275 MB I decided not to install and canceled the installation process.Since then some updates do not install, some others do install just fine though.System charcteristics:Vista Ultimate 64-bit, MS Forefront, no other anti-virus or malware installedSFC stops at 21% with the following:--------------------------Beginning verification phase of system scan.Verification 21% complete.Windows Resource Protection could not perform the requested operation.Thanks!
