Download the Eudora Pro 3.01 updater from the Qualcomm Site and replace the SETUP.INS file with this one. The way to do is is to run setup. When the InstallShield Autoextractor finishes and you see that giant blue screen, go to your Windows\temp directory and copy the files in there to another place. After you do this, cancel the install, copy the file in this zip to the directory where you copied the other files, and then run setup from there. You should now be able to install Eudora PRO! If you have any problems, let me know.
