When Scenario Navigator crashes on startup

[RChin]

When Scenario Navigator crashes on startup, before a window was opened then most likely the registry permissions are not set correctly.

DISCLAIMER: modifying registry settings in MS Windows should be done with care by a qualified system administrator, because when you do it wrong MS Windows may not work any longer and important data may get lost for ever! The instructions below come WITHOUT ANY WARRANTY. Following these instructions is for YOUR OWN RISK. Systems Navigator and/or its staff are NOT RESPONSIBLE for any damage whatsoever.

To correct the registry permissions (in Windows XP):
- Login to MS Windows as a user with Administrator rights.
- Start regedit (click Start menu, click Run ... , type regedit)
- In the tree to the left expand My Computer, HKEY_LOCAL_MACHINE, SOFTWARE, Systems Navigator, Scenario Navigator.
- right click on Scenario Navigator and select "permissions" from the popup menu.
- In the dialog window select the user that you want to grant access and check "Full control".
- Click OK, and close regedit.

Next, log out as Administrator, log in as the selected user in MS Windows and try to run Scenario Navigator.
