Unmounting while in use

[Findas]

Hallo

my Problem with DT is, I am Installing from an Image but when the Installation gets to a special Point the image just unmounts.

I haven't found a post on that so sorry if I am posting on a normal problem.

I use DT 4.09HE

SPTD is updated to instal 4.091

thanks gor the help

Do you have SecureMode enabled?
How did you create the image (program and settings used), and which program/game is it?
