Step 3 : Under "Make changes to your user account" click on the "Change security settings" link.
Windows Vista support page
Microsoft Windows Vista attempts to provide greater security when running programs. Sometimes this can cause problems when these programs need Administrator rights, e.g. like DVD-Audio Solo to access the DVD Writers.
There is also a known problem with Vista that can cause a failure of programs like Windows Explorer, Internet Explorer, Outlook, DVD-Audio Solo to fail with errors like "program has stopped working" or "Error code 000000B7". This problem is supposed to be fixed in the upcoming Vista Service Pack 1 from Microsoft.
In the meantime and if you encounter these problems, please try the following workaround(s), which may require disabling User Account Control (UAC) and/or Data Execution Protection (DEP). If you do not want to disable UAC for all your programs, we suggest you create a new user account with Administrator rights and UAC disabled for use with these programs requiring UAC off.
1) First Make sure Solo runs with Administrator rights
2) Error code 000000B7 : Disable UAC
3) Error "dvdasolo.exe stopped working" : Disable Data Execution Protection (DEP) for dvdasolo.exe. This is more likely to happen on recent hardware.
Make sure DVD-Audio Solo runs with Administrator rights
Right-click on dvdasolo.exe in the installation directory, select the Compatibility tab and make sure "Run this program as an administrator" is checked. If it is not, check it as illustrated below and restart DVD-Audio Solo, this may simply be the problem (if it is unchecked, you would receive an Error code 000000B7).
Step 2 : Click on one of the user accounts, for example the Guest account. Under the user account click on the "Go to the main User Account page" link.
Disabling Data Execution Protection (DEP)
Step 1 : Open Control Panel, under User Account and Family settings click on the "Add or remove user account".
