Hi Frank,
To resolve your issue we would like to know:
1) Is Vsp.sys ( AOFO Driver ) on your machine? If yes, That means AOFO is
installed and you can not deleted it.
2) Please check in Tools-> Options -> Advanced open file and check if the option is checked and grayed out. If this is the case, that could cause the problem. To uncheck it, you have to install AOFO-> uncheck the option-> uninstall the AOFO if not needed.
3) You can do it through registry: HKLM|Software-> VERITAS->Backup->Exec->Engine->Backup|->Use Open File Option.
Set this Key to 0 if it is set to 1.
Thanks
