CAUTION : We strongly advise against downloading and copying netfx.msi to your appropriate Windows system directory. Compact typically does not release Tiff Viewer 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 netfx.msi and all other MSI files for Tiff Viewer. An incorrectly installed MSI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
