I got the same thing...... I renamed the file update.zip and put on the SD card and when I went to run it it tells me it can't find update.zip.... plugged the phone back up to the computer and it's there update.zip... removed and reinstalled but it's still telling me it can't find that file and aborts installation????
Loading up now!!! Will report back when its complete.

Please be aware any update.zip floating around for EVO are not final and may cause problems. Official updates are coming OTA next week!
Update:
Success. Froyo installed! Only thing to add to my previous instructions are to select reboot on the menu when it tells you to and then let it do it's thing.
Not sure if this has been asked or not, but are you sure you did not rename the file to update.zip.zip?
If this has been addressed I apologize.
I am looking at it and at the bottom of my screen when looking in the SD card on the phone (from my computer) it says update.zip the date modified and date created and the compressed (Zipped) Folder and size 84.4
GUYS, if you are renaming it .zip make sure it's not .zip.zip...meaning if you don't have extensions showing (like .doc) just name it update.
