This the message (and the problem, too) in DDRK3_setup.log file:

Action Start: SavePropertiesToMetabase()
Trying to get the IIS://Localhost/W3SVC/1/Root/DAVCatalog object

Action Start: SendMSUPGRADE()
ERROR: -2147024891, Description: Access denied.
, Details: Could not send the MS-UPGRADE command

Can someone help me, please?

Thanks
