Today I updated the SharePoint Feature Manager to fix an interesting bug I found.
On my development VPC that was upgraded from B2TR to RTM the path to the Features directory was:
C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES
On my development VPC that has a fresh install of RTM the path to the Features directory is:
C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\FEATURES
The change in capitalization of the Web Server Extensions directory, highlighted in bold above, caused a path replacement inside the SharePoint Feature Manager to fail on the fresh install of the RTM build. I've fixed the bug and the application will now work properly on SharePoint installations that were not upgraded from B2TR, as well as SharePoint installations that were upgraded from B2TR to RTM.
