but I notice that no links have been created in the Community folder.
This is the main issue and it just shouldn't happen, if the drive is formatted in NTFS and the installer can run with admin rights, links will surely be created. Also, it's even more strange the fact that the same installer running under the same conditions is able to create links for FSDT Zurich, the code is clearly the same.
Are you sure you don't have real folders there ?
Also, you say you have your Community folder on F: but, have you moved it in the correct way ( editing the UserCFG.OPT file with the path of the CONTENT folder, the one that *contains* both Community and Official ) or you did something else, like linking just the Community folder there, which is the wrong way to move the Content elsewhere ?
