Question

When I try to install extensions into Dreamweaver CC, I get the following dialogue box in the Extension Manager CC:
"Failed to update database. The extension will not be installed."
What may the problem be?

Good day to all,
The problem that we were having was caused by a case difference between two folders, like Carl pointed out. The line that created the issue was written like this:
<file source="File1.htm" destination="$dreamweaver/Configuration/Shared/MyExtensions"  />
<file source="File2.htm" destination="$dreamweaver/Configuration/Shared/myExtensions"  />
The correct folder was with an upper case ("MyExtensions").
The extensions are now installing correctly however it seems to take significantly longer to install than on previous versions of EM (even previous version of EM CC). Has anyone been experiencing the same long install time? This only happens on Windows OS. On Mac the extension is installed pretty fast.
Any idea how I could lower the install time? We do have a long list of files. Maybe try to use only folders instead of individual files?
Cheers,
Andrei
