I have the right permissions (as admin), and the Add-In installed properly; in edit-mode, on the "Microsoft Add-In" tab, under tab "1. Install", the button "Install version 2.2" is now dimmed down.
However, under tab "2. Activate", nothing happens when I push the Activate button.
This is a clean install - I've done nothing except installing the template site and then installing the Add-In by pushing the button on tab "1. Install".
If you're running on Windows Vista the activation problem is probably caused by higher security settings for IE. The activation procedure writes a registry key, but this is not allowed with the default security settings in IE on Vista and fails silently. The easiest solution is to add the site to your trusted sites zone.
I've now also installed the new SP1 template files - and the problem is still here.
I'm running a standard installation of CMS5 R2 SP1 (with the SP1 templates) on Windows XP. I'm using Windows Internet Explorer 7.
Still no luck with the MS Add-In...
What url are you using (localhost or machine name)?
When you install EPiServer (version 5) the siteUrl setting will automatically be set to your machine name. You can then run your site both using localhost and value from siteUrl.
If you activate your office add-in, it will be activated for url set in siteUrl. So, if your're browsing the site using localhost (and have macine name as siteUrl), it will look as the add-in hasn't been activated.
Related question (should perhaps be it's own thread?):
From MS Word, when clicking "Publish to EPiServer CMS", the dialog for connecting to my EPiServer site only lets me type the password - not the username.
How can I change the username with which to publish the document?
(E.g. suppose that I have several usernames in my EPiServer database... How can I select which user to log in as?)
