Download LyncMUI.msi Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying LyncMUI.msi to your appropriate Windows system directory. Microsoft typically does not release Office MSI files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing LyncMUI.msi and all other MSI files for Office. An incorrectly installed MSI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
