I can't get the Windows FM 5.0.3 update to install.
I've already installed the previous updates, so I'm currently running using FM 8.0.2 (Version 8.0p273). When trying to install 8.0.3 it downloads the files and then gives me an error message:
"You do not have correct version of FM install on your system. This patch installer will work only with Version 8b273 build. Patch installer will quit now."
Followed by another message:
"Adobe FrameMaker 8.0.3 Update failed to install.
