Symantec backup exec 2014 Exchange restore Restore - Exchange Database

I have been trying to complete a restore for a Exchange Server  backup on both the mailbox and individual level have not been successful.  I have received different errors or different results.

I would like to know if there is a way, to move the following staging directory "$Backup Exec Default Data$" from the "C" drive to a different volume/Drive that has more then enough space to handle the staging data dump?  I have tried the following suggestion to no avail.

1. The Windows Registry fix which forces the "OnHostTemp" value to force the writing to a different drive/volume and it was a no go
2. I have changed the GRT settings as picture below:

I read a tech notes that I could use BEUtility and move the "$Backup Exec Default Data$" from it's default location to a different location, is this true?

Please, advise
