I have the exact same issue. I have searched the Forums and written multiple emails and still cannot update my AutoViewer Lightroom Template to AutoViewer Pro.

I copied the autoviewer.swf file from my purchased version of AutoViewer Pro and attempted to paste it exactly as described below:

4.2 Upgrading the Lightroom AutoViewer Template

To upgrade your Lightroom v2 AutoViewer Engine to AutoViewer-Pro:

    * Copy the AutoViewer SWF that comes in the Pro download (at \web\autoviewer.swf) into the AutoViewer Engine folder, replacing the existing file.The path to the AutoViewer Engine folder is as follows:
          o Windows: C:\Program Files\Adobe\Adobe Photoshop Lightroom 2\shared\webengines\autoviewer.lrwebengine
          o Macintosh:Applications/Adobe Lightroom 2.app/Contents/Plugins/Web.lrmodule/Contents/Resources/galleries/autoviewer.lrwebengine (To browse inside a package use ctrl-click and select "Show Package Contents").
    * Restart Lightroom. Any galleries you create from now on will use the Pro swf.

After restarting Lightroom, there was no difference in the web gallery settings. I then deleted the original viewer.swf file leaving only the recently updated autoviewer.swf. I restarted Lightroom once again and when I tried to open the AutoViewer in the web module, the gallery would not respond. The loading bar kept flashing rapidly as if it were missing a file to continue to load the gallery. It was not until I replaced the original viewer.swf file that the web gallery responded, but obviously with the original appearance.

I just redownloaded what I believed to be the latest version of TTG AutoViewer. Loaded in Lightroom it says TTG AutoViewer Gallery 1.2 But I have seen other peoples posts about a version 1.4. I have tried searching to be able to update my version to 1.4 hoping that would solve my problem, but every link to 1.4 updates are dead. Please point me in the direction I need to go.

Thanks!

Is there anything that I can do?
