I am trying to install the same skin on multiple sites from the Site-->Admin-->Extensions-->Install Extension Wizard. The skin installs fine on the first two sites, but on the 3rd site I get " A critical error has occurred. Sequence contains more than one matching element" when I try to install. If I go through the hassle of renaming the skin file in the manifest, I can get it to install.

I don't want to install the skin at the host level because of the way it does some special templating and I don't want to share that across sites. I had been able to do this previously, having installed the same skin on 3, 4, and 5 sites at the site admin level before I upgraded from DNN 7.0.5 to 7.2.

(I debated which forum to place this on, so if someone wants to move it to  a better locale, please do)

Here is the full error:

that usually indicates that the skin has already been installed i.e. there are 2 copies (usually one installed in the host portal i.e. portals/_default, and one attempting to install within a site portal.

Why not install it on the host portal and not use where you dont want to use it then activate it under site settings for the specific portal?

Thanks for the replies so far. I can't (ok- operationally don't want to) install at the host level because this skin allows the site administrator to customize it though a module that modifies a skin config files (which is pretty awesome). If I install it at the host level one admin would end up redesigning some other persons site and not even know it. Imagine the irritated calls/emails then!

I checked the _default portal and there are no files from any of the skins there. It is definitely related to the number of installs on different sites: 2 sites ok, 3rd site = error. I would classify this as a bug, since installing the same skin at the site level could be needed for any number of customization reasons. My current options are to rename the skin package for each site install (not a fan), find a work around/alternate install method, or get this as a bug report and wait for a fix (how and how long will I have to wait).

Still open to ideas....
