I have also tried the following to install NIS 2009.
[The first 2 were suggested by Norton support]
Normal mode install over NIS 2008.
Uninstalled NIS 2008 and safe mode install of NIS 2009.
Ran Norton removal tool and reinstalled Ghost 12.0 and NIS 2009.
Uninstalled NIS 2008 and Ghost 12.0. Installed Ghost 14.0 [trial] and NIS 2009.
I checked if I could mount and dismount an image. The same error occurred cannot dismount .v2i unspecified error (error ec8b0013) with both Norton Ghost 12.0 and 14.0 [trial].
When I uninstall NIS 2009 both Norton Ghost 12.0 and 14.0 work. I can mount and dismount a .v2i image no errors.
