[PS] C:\Program Files\Microsoft\Exchange Server\V15\Scripts>.\Troubleshoot-CI.ps1
The troubleshooter failed with error:System.InvalidOperationException: Couldn't read registry key:SOFTWARE\Microsoft\ExchangeServer\v15\ContentIndex\CatalogHealth\{017222b7fdf254-4111-bd99-619687ghg1j96}At C:\Program Files\Microsoft\Exchange Server\V15\Scripts\CITSLibrary.ps1:1023 char:9

This is due to the location of the catalog health information has moved location in Exchange 2013 and a the script is calling "CITSLibrary.ps1" that contains the old location - and it looks like MS never updated the scripts.

At the time of writing I am not aware of any work-around to get Troubleshoot-CI.ps1 working.
