Embarrassed to admit I can't get it to work

I'm very much looking forward to using BetterZip quicklook on my Mac (leopard). I've tried other "solutions" with less than satisfactory results.

I installed BZQL as per the directions. I applied the Terminal commands, restarted Finder, rebooted, etc. No luck. When I press Spacebar on a selected Zip archive, I only see the icon. No contents or additional information.

I'm usually fairly adept at this. But I don't know much about the inner workings of the quicklook feature coding, and am clueless as to where to look or what to do next.

Any suggestions (preferably helpful) would really be appreciated. Thanks!

Which version of Mac OS X do you use? To which folder did you install the BZQL generator? Do you have other QL generators for archives installed?

You can run this command in the terminal to get some diagnostic output (replace the last bit with the absolute path to your file):
qlmanage -p /Users/robert/Desktop/testfile.zip
What does it say in the last few lines?

Thanks for the reply. Sorry I didn't include more info to begin with. I wasn't sure where to start.

To answer your questions:
I'm running OS X 10.5.8
I installed BZQL in Macintosh HD/Library/QuickLook/
I do have other QL generators, but I don't know if they might conflict. Here's what is installed (in that same folder) -- (they are all "*.qlgenerator" unless indicated otherwise) BetterZipQL; colorxml; flv; Folder; GBQLGenerator; GISLook; iWork; Pacifist; Perian.component; quickchm; SneakPeek Pro; Stuffit; Suspicious Package; SWFPreview; VMWare Fusion QuickLook

I ran the command you provided (thank you!) adapted for my system:
"qlmanage -p /Macintosh HD/Library/QuickLook/BetterZipQL.qlgenerator"

Here's the response I got:
009-12-25 13:49:36.437 qlmanage[13149:10b] [QL] Succesfully activated built-in quicklookd sandbox profile

2009-12-25 13:49:36.684 qlmanage[13149:620f] [QL] Thumbnailing for file://localhost/Macintosh done (No image created).

I hate to admit that I don't understand all of what this says. I would be very grateful for any help on this.
Thanks,

I didn't mean you should replace the last part of the command with the path to the generator, but with the path to your zip file (or whatever format your archive has). Next, try to move the StuffIt generator to another folder, e.g., your desktop then restart the Finder or reset the QL system with qlmanage -r.

Sorry about that. I misunderstood. I'm still coming up to speed, but should have seen what you were suggesting.

I ran the command again (this time directed to the correct testfile.zip). The response indicated that the Stuffit generator was creating a conflict.

I edited the plist file for the Stuffit generator to avoid having it handle Zip files. That did the trick! I should have figured as much.

Thanks for all your help!

Great!
