Installation problem vb 4.2.3

[Lloyd32552]

Dave,

That was the first thing I thought of, too. Upgrade.php is in the installs folder. I simply unzipped the archive and uploaded everything.

A couple more things I've tried -
I deleted the entire system and uploaded 4.2.2 and then ran install and got the exact same message.
I then deleted that entire system and downloaded a fresh archive of 4.2.3 and uploaded it. I was surprised to see that the install folder did not contain a copy of install.php, though. On a lark, I uploaded install.php from 4.2.2 and got the same messages as before.

A couple things - the server is running php 5.4.

Any ideas? Is there an installation log that will tell me more than the message I've seen?
