Started receiving error today:

While executing onClick in dmxThumbnailGallery10_install.htm, the following javascript error(s) occurred: at line 1 of file c:\users\<path>\AppData\Roaming\Adobe\Dreamweaver CS5\en_US\Configuration\shared\DMXzone\Scripts\dmxInstaller104.js:getDocumentDOM: Argument number 1 is invalid

If I ok through I get the normal dialogs, but then it hangs during the actual installation.

Hello Debbie.

Did you tried to clear DW cache file yet?:
Clearing Dreamweaver's cache
Did you notified exactly when the error begins to show?

Regards:Vulcho.

Yes to clearing the cache. It started yesterday, although I've not recently re-installed ATG. Not sure why it came up at this time...

The error starts as soon as I click to install ATG. This pops up as soon as Dreamweaver opens.

The error occurs as soon as I click install. I go through the screens to add serial, username, etc. then when I click install the error appears.

Sorry, I keep misreading your post to me.

As soon as I ok the error, I get the installing extension screen with the installation progress & processing file that goes nowhere. I have to click the x to cancel and get the warning that the extension hasn't been installed.

I've recreated my dreamweaver preferences and will let you know if I have any issues after reinstalling all extensions.

Hello Debbie.

Please notify me about the progress on the issue.

I've tried to recreate your issue on couple machines but was unable to receive such error.
Do you have CSS3Shadows or Ajax Datagrid extensions installed ?If yes please make sure that they are updated to lattest version. For installing and updating the extensions you can use DMXZone Updater, which is huge time saver in my opinion.

Regards:Vulcho.

I don't seem to be having the issue now that everything's been recreated. Using the updater sure made things easier to update with the exception of my older extensions from the presentation bundle and th eghtml bundle -- they didn't recognize my username or password so I left them uninstalled since I don't use them any longer. Thanks for the follow up!
