I followed the instructions on upgrading to 1.0 M021 and all seemed to be going well. I backed up the SharePoint and SQL data. Uninstalled Windchill Product Point (kept data) and then attempted to reinstall per the instructions and I get an error saying the IIS website I have selected is already in use by SharePoint. This is the error I get
Any assistance or thoughts on this? I am aware of a possible workaround for SharePoint via the MS KB
http://support.microsoft.com/kb/927376 But I do not think I should need to do this, this is apparently something with the Windchill product installer.
