Why is my software tied to the permission level of the login user? If in NT/2000/XP the user does not have modify file permissions for my software?s folder, then my software can not edit it's own files! What am i missing? i know that my software should be able to modify it's own data files no matter who is logged on. My software is written in VB.

You are correct.  Permissions are based on the USER running the program not the program itself.  If the logged on user starting the program doesn't have modify permissions for the file or folder where the program is located, the program cannot be modified by that user.

You are no longer in the free and clear world of DOS and WinNT and its successors have real security.  If you want to perform an operation that you don't have permission to perform, you will be stopped!

My software is auto started by Windows, not a user. This is done in the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run registry key. Is there a way to have Windows auto start my software and not have it at the logged in users security level?

The HLM\....CurrentVersion\Run is processed on your behalf by Windows but all of these apps run in the context of the currently logged on user and they start at logon time.

If you need to run something under a DIFFERENT user account, you must use a SERVICE and have the Service Control Manager (SCM) start it at boot time.

Not that I've done this but...

You may be able to use the LogonUser() and CreateProcessAsUser() etc to execute code in the context of another user who has the required privaledges.

Sorry, sometimes reality intrudes on our world.  It's just the way it is.  You can either do it the right way or stick with DOS where anything goes...
