I just installed 1.7 on Zen 1.3.8a. Origonally I tried upgrading from 1.6.7 but had a few issues so I decided to remove 1.6.7 and install fresh. After running the uninstall.sql for 1.6.7 , overwriting all the files with new 1.7 files and setting up my Google Base account info again I get an error when trying to generate a product feed.
Basically the last line in the pop up windows states....

Processing: Feed - No, Upload - No

I have uploaded the new files 3 times now, and have tried rerunning the .sql script as many and Im stumped.
One other thing I am noticing is that the first line of the feed generation pop up windows is this:
Google Base Feeder v.1.6.16 07.03.2008 23:40:59 started 2008/10/06 00:55:40
Shouldnt that say v.1.7 ??

I have this on a local test server in my office as well and the feed generation works but the upload does not. Same info though on the line above-- Google Base Feeder v.1.6.16

Any suggestion in what may be causing this? Im not as concerned about versioning info as long as the feed generation works.

TIA
This may help you.
1. BACK UP YOUR DATABASE
2. Go into PHPMYADMIN browse the 'configuration' table
3. Sort by 'configuration_key'
4. Delete all rows that contain configuration_keys that begin with GOOGLE_BASE or GOOGLE_FROOGLE
5. Run the install for the latest version Google Base Feeder v1.7.0
