I decided to try installing the Podcast Kit for SharePoint on one of my Virtual Machines.
After a few hours of installing all of the pre-requisites I realised that I would be better off installing it on my Windows Server 2008 VM which already has VS2008, .Net 3.5, Silverlight etc installed.
After my first attempt and the amount of editing I was doing of web.config and the number of features needing to deploy, I decided the best thing would be to create a completely separate web application and site collection to host PKS.
When I went to install the pre-requisites, I tried running install.exe, but was not able to load the solutions through the UI. I got the following exception in the event log;
SPInstallCab:Exception while deleting expand directory C:\Users\Administrator\AppData\Local\Temp\1\podcastingkitforsharepoint Access to the path 'schema.xml' is denied.
the message resource is present but the message is not found in the string/message table
I had to use the install.cmd instead of the GUI, and that appears to be working okay.
I am installing the July Tech Preview which currently only supports Silverlight Beta 1, but Beta 2 player does seem to be working for me.
