Remember that Administrator doesn't always have rights to directories, etc.. you can set folders and items to NOT get their parental designation.
Click on folder, or item(s) that you want installed...
make sure that the security allows YOUR user to install into all directories!
I've had that happen.. the Admin group was setup, but not my individual user.
My solution = turned off all user exceptions and all "EVERYONE" rights to all folders. Yes, security(off)...
/ramble off.
