Thanks for your kind and quick response. I enclose information that could be helpful in resolving the issue:
1) I use Windows XP SP3.
2) The ERUNT software comprises at least two programs ERUNT.EXE and AUTOBACK.EXE. Software documentation indicates that
------“
AUTOBACK is a command line utility”
3) I uninstalled, cleaned program traces and reinstalled ERUNT. This time, as an alternative, I've installed in a directory created by me (C:\Programs)
4)
Under the Windows Administrator account both programs are running without any problems.
5) Under the limited user account must be included in Surun (surunners group) with the options:
------
Automatically start this program with elevated rights and never ask for a Password
------
Start the program with elevated rights automagically
but
only succeeds ERUNT.EXE
6) The program documentation
http://www.larshederer.homepage.t-online.de/erunt/erunt.txt
reports the following:
------“
Note: To ensure proper operation of ERUNT, you should be logged in as a system administrator.”
The backup can be outside the WINDOWS system folder, but not recommended for the following reason
------“
You can also simply leave the default, which is a folder named ERDNT inside your Windows folder, the advantage being that you have access to this folder from the Windows Recovery Console in case Windows does not boot anymore”
7) To confirm your suggestion I created a file ERUNT.ini amending syntax to yyy.mm.dd, both in the user account as the Administrator. Currently the message in the user's account of surunners group is as follows
------“
Unable to create folder C:\WINDOWS\ERDNT\AutoBackup\2010.04.20”
8) I tried to run the program AUTOBACK.EXE in the user account under all conditions that have occurred to me. In my opinion the problem is not parameters, but access to directories. There are basically two situations:
a) In the system directory with the command:
------C:\Programs\ERUNT\AUTOBACK.EXE %SystemRoot%\ERDNT\AutoBackup\#Date# /noprogresswindow
the result is
------“
Unable to create folder C:\WINDOWS\ERDNT\AutoBackup\2010.04.21”
b) In the alternative directory of the program itself, with the command
------C:\Programs\ERUNT\AUTOBACK.EXE C:\Programs\ERUNT\ERDNT\#Date# /noprogresswindow
the result is
------“
Error saving file. C:\Programs\ERDNT\AutoBackup\2010.04.20_14:21\SECURITY!. Continue with the next file? (RegCreateKeyEx 5 - Access denied)”
9) Before I write to you I made several Internet searches for a solution.
With the chain:
------
Unable to create folder \ERDNT\AutoBackup
there are several entries. Among the top 20, most belong to the underworld of infectious panic. The closest to the problem seem related to the UAC of Windows Vista, but provide no solution.

And with the string

there are several comments. For example, this:

whose successful outcome I could not reproduce despite uninstalling, clean traces and reinstalling.
Thanks for your interest and your help
