Hi,

When installing MultipleFileUpload v 1.1 in Umbraco V.4.0.4.2, the installer is able to copy all the files.

When it needs to create the DataType, new tab in media folder and update the web.config, it fails (see message below).

I tried to do the manual install, but when going to a folder in the media section, it shows a similar error (key not present).

Also tried this but same problem.

What causes this error?

Thanks

Javier
