Yes - dnc4U works 100% on Windows 7!

However, you might sometimes be drawn to the conclusion that, along with thousands of other programs that used to work just fine under XP, it won't work! Don't worry it does work. The security model that is used in Windows 7 just means you may have to tweak dnc4U to run as intended. Many users install straight out of the box with no tweaks at all. Below are some useful tweaks if your dnc4U will not start after installation.



Here's a quick guide to problem solving installation problems.

You initially need to install the dnc4U program with administrator rights to make sure that all files and components are copied, installed and registered in Windows properly.

In addition, the first time you run dnc4U it has to be done with full admin rights. We suggest that whoever installs dnc4U ticks the "Launch dnc4U" box so that dnc4U can create some initial settings ready to start at the same time.



In the majority of cases, say for example you bought a laptop, then admin is the default user, but in larger corporate environments, IT techies may have restricted user access priveliges. After installation the user does not need admin rights - but he needs to be able to read/write & execute in the dnc4U folder. This is so that he can save data off the cnc, as temporary files are created and then destroyed. Almost all installation and consequent program problems are due to insufficient access priveliges.

After Installation

What sometimes happens is that the initial installation of dnc4U is made (which has to be done with administrator priveliges) then a user with lowers priveliges tries to run dnc4U and nothing at all happens. Running-as-administrator solves this problem in the majority of cases - that is why after all this huffing-and-puffing over extra computer security, Microsoft had to have this option - otherwise thousands of programs would just not run - so it is a 100% safe option to select - and is the key in many cases to getting dnc4U working properly.


Run As Administrator
If you right mouse click the dnc4U icon on your desktop, you can click "Run As Administrator". All this does is raise your priveliges temporarily whilst running dnc4U. In essence it means run as a trusted program, there is no danger of users running amok and destroying the computer with full administrator rights. Once the icon has been clicked, Windows remembers the setting, so you only have to do it once.



What usually happens is that the initial installation of dnc4U is made (which has to be done with administrator priveliges) then a user with lowers priveliges tries to run dnc4U and nothing at all happens. Running-as-administrator solves this problem in the majority of cases - that is why after all this huffing-and-puffing over security, Microsoft had to have this option - otherwise thousands of programs would just not run - so it is a 100% safe option to select - and is the key to getting dnc4U working properly.


Compatibility Mode
If you do experience some incompatibility problems, or dnc4U will not run despite running with full admin rights or running as administrator, then you could try running in XP mode. Unlike Vista, Windows7 does seem to have some effect, Microsoft say that it runs "virtualized" as XP from within Windows 7. What we have found is that this invokes the UAC every time asking if it is OK to run in this mode. If it makes dnc4U work, but the UAC really annoys you with a pop-up every time, then you can modify or turn off the UAC - see below.


Disable the User Account Control (UAC)
The UAC is very, very, very annoying. This is the pop-up that interrupts every time you want to run a program. If you can turn it off, do so, if your IT manager will allow it, turn it off it makes life so much simpler.

1. Open Up Control Panel - Select System and Security - Select from Action Center - Change User Account Control Settings



2. Move the slider down until the UAC stops annoying you




Data Execution Prevention

Windows 7 can sometimes prevent legitimate programs from working as it "thinks" they may be malicious and so prevents programs from executing various security flaws in Windows. dnc4U is quite safe, we've got better things to do than mess about with your computer. Windows will notify you with a pop-up windows with the words "dnc4U has stopped working - Windows will now close down the application".


We have received this message too and have got round this by turning off the "Data Execution Prevention", "DEP" settings in Windows.

1. Go to Control Panel, click System and Security - click System



2. Click the Advanced System Settings



3. Click Performance - Settings button




4. Click Data Execution Prevention tab - select "Turn on DEP for all programs and services except those I select".



5. Click the Add button and search for the file "dnc4u.exe" and then click the Open button.



6. dnc4U is added to the list, tick the box next to it. Then click OK.
Windows will probably say that the effects will take place next time you start the computer.
