UPDATE:

Unfortunately, after restoring the original files, I still get the same two errors during program loading.

I also get (every other load) the message:

     Some plug-ins have been updated. You will need to

     relaunch Illustrator for the changes to take effect.

when the app is finished loading.

And the Window menu has duplicate entries for:

     Appearance

     Appearance

     ...

     Graphic Styles

     Graphic Styles

     ...

     Layers

     Layers

     ...

     SVG Interactivity

     SVG Interactivity

Hi Rama,

You may have identified the problem. I didn't realize Illustrator would scan all files in its installation folder tree, so I had my backup in a bad location.

I have moved the backup, but when you say to delete the preferences, do you mean JUST the AIPrefs file, or ALL the files (about 12 files) in the settings folder? Or perhaps even all the other folders in the settings folder (Brushes, Composite Fonts, Graphic Styles, ..., Plug-ins, ..., Workspaces)?

Thanks,

Allen

UPDATE:

Before determining exactly what to delete in the Preferences folder(s), I launched Illustrator, got the same error messages one time, and now on all subsequent launches there are no more errors, and all the duplicate plugins have disappeared.

So the problem appears to be solved without having to reinstall Illustrator.

Thanks very much for the help. I would still be interested to know what parts of the Settings folder tree could be safely deleted, if you have a chance to reply.

And of course I'm tempted to try the HTML5 pack again, but I'll have to wait until I've completed some important work in Illustrator today.

Allen

Thanks!

(OT)  Now I just have to figure out how to get the updates for Dreamweaver 5.0.3 and Premiere Pro 5.0.2 to install. I've tried temporarily moving their settings folder(s) but the installs just don't work.

Can you perhaps direct me to the proper forum for reporting this? There doesn't seem to be a forum for Updater.

Thanks,

Allen

UPDATE:

While using Illustrator, I found that it repeatedly crashed whenever I clicked on the control bar's font color control.

Figuring I had nothing to lose after all this plugin shuffling, I re-installed the HTML5 pack files, and now everything again appears to work.

I'll post again if any other anomalies turn up.

It's worth noting that something about running Illustrator the way I did (with duplicate plugins) did not get fixed when I restored the proper original environment. However, it appears that the side-effect was canceled out once the HTML5 files were back where they belong. This means, of course, that if I were to require an uninstall, restoring the original 5 files might not actually work.

This implies, in turn, that simply backing up the 5 updated files might not be sufficient for installers of the HTML5 Pack. (However, it's possible that after the HTML5 Pack has run successfully, replacing the 5 files might not introduce side-effects.)
