"menu can't be actualized" error when installing/updating extensions

hi. when I try to install or update new/updated extensions, I get the error message that "Menus can't be actualized, extension will not be installed" (translated from German). I did the installation procedure exeactly as proposed on the WA-web (starting extension manager from Dreamwever, closed Dreamweaver prior to starting the installation; I also stopped the Anti virus software and quit all other applications). I'm working with DW CS4 on Windows XP SP3. Any hint which could help me solving this issue is very welcome. Thanks! Thomas

This type of error usually happens when an already installed extension has updated the menus file for Dreamweaver and the file is no longer updatable. There is likely some change in the file that makes it not recognized as being able to update or something like this.

The only real way to redo this file is to remove all of the extensions you have installed and reinstall them. The error may still occur for you though even after this. The next step up would be to completely remove the configuration folder and have it be recreated, this would also force you to re-install all of your extensions.

It is possible that not even this will resolve the issue though, in which case a re-install of DW may be needed. The problem with this error is that it is usually a sporadic one that cannot be reproduced and therefore does not have a definite method to deal with it.

If you would like to delete your configuration folder to see if that will help eliminate the issue here is a link to a post that gives the exact instructions for this:

I had the same problem. Deinstalling all extensions and reinstalling them solved the problem.

Thanks for posting back on the confirmation of this. It is not an error that comes up often so I sure that any others that get this will be happy to see this thread.
