SYMPTOMS
While installing Genie Backup Manager (GBM) on Windows Vista, the following error occurs with the message:
Internal Error: Failed to expand shell folder constant “userappdata”
CAUSE
This problem is caused by a Vista conflict.
RESOLUTION
Set the My Documents folder to its default values as follows:
Using Windows Explorer, right-click the My Documents folder → Properties → Select the option for returning the position to its default value.
C:\Documents and settings → All Users Documents → under properties you will see attributes and the settings for “read-only”
Setting back the default value for My Documents is just a workaround, which usually fixes the default read/write rights for the My Documents folder.
