When attempting to run Service Accent, you receive the following error message:

Some Windows operating systems have an extremely complicated security model that prevents applications executed by users with standard permissions from running correctly (it prevents access to certain, system folders)

Click on the Windows Start button and Type 'User Account Control' into the Search Programs and Files section, you should then see an item called Change User Account Settings. Click on this to open it and move the slider down to Never Notify and click OK. You will need to restart your workstation in order for the changes to take affect.

Alternatively if you prefer not to disable User Account Control then you can try the option below:

Right click the Service Accent shortcut and select Run as administrator.
