Hello,

I am using Windows Installer 1.52 and when I install my application on Windows 2000 I am getting

"Files are protected by Windows" And it says these files cannot be updated.

Error comes for two files - Triedit.dll and DHTMLed.dll

What does this mean ? This error doesnt appear when I install my application on Windows NT.

Thanks,
Devang Parmar.

Windows 2000, XP, and ME contain code to protrect system files from ad hoc upgrades by third parties.  These files are only meant to be altered by authorized installations such as operating system service packs.

You should check for the operating system and not install contentious files.

You may also need to display a message/error to the user to upgrade to a later service pack if your product needs a more recent file.
