Admin 404 Not Found The requested URL was not found on this server

Simpler way:

- delete the zen-cart-v150-full-release-1230201 folder from the server
- now your catalog folder should be empty, right?
- so, now upload the files-and-folders from the zen-cart-v150-full-release-1230201 folder on your PC to the catalog folder on the server
- run sitename.com/catalog/zc_install

I tried that early on thinking it would work. It brought me to a page with:

Parent Directory -> Took me to my regular site
zen-cart-v150-full-release-1230201 -> Just hung there

One of us is missing something here. I don't have a clue what you mean by that or how it relates to my last reply.

I tried that, removing the 'zen-cart-v150-full-release-1230201' It just showed a header.

Anyway... I've been messing with this long enough, and not even treading water, I've been working with with osCommerce also. I have it up, and all coded properly, I even have the theme color I wanted. It was up and running well, not perfectly on initial install. After a little debugging.. I've tried it, have had friends try it... no errors or warnings yet. I thought they were close to the same..or close, but the latter installed and worked much easier and faster.

I do truly thank everyone for their time.
