    Running DisplayMate on 64-bit Windows Systems    
Using the free Microsoft XP Mode in Windows 7 is Easy

DisplayMate runs on all 32-bit versions of Windows 7, Vista, and XP
If you get the message "The version of this file is not compatible with the version of Windows you're running" then you are trying to run DisplayMate on a 64-bit version of Windows. DisplayMate normally runs on 32-bit versions of Windows but you can run it on 64-bit Windows in a number of ways...

Running DisplayMate on 64-bit Windows 7
If you don't have a 32-bit Windows system that you can use or borrow then the easiest way to run DisplayMate on 64-bit Windows 7 systems is by using XP Mode which is a free Microsoft download for the Professional and Ultimate Editions of Windows 7. It comes pre-configured with Windows XP already installed and ready to run. If you have one of the Home Editions you will need to upgrade to the Professional or Ultimate Editions. Alternatively, you can instead use one of many other available Virtual Machine Emulators and install a 32-bit version of Windows 7, Vista, or XP in it.

Downloading XP Mode from the Microsoft Website:
Click the link below which has an Introduction to the XP Mode and a link to Download it from the Microsoft website.
Install and Use Windows XP Mode in Windows 7

Direct Link to the Microsoft Download Center page for the XP Mode:
XP Mode Download
Click the Red Download button
Then Select WindowsXPMode_en-us.exe
Then Click the Next Button to start the download.
Run the downloaded file WindowsXPMode_en-us.exe to start the XP Mode installation.

Launching DisplayMate for the first time in XP Mode:
You can automate all of this by adding a Shortcut for DisplayMate on your Windows 7 Desktop, as described in the next section.

1. Launch XP Mode, switch it to full screen, open My Computer, and then insert the DisplayMate USB Drive and note what device it is, most likely E. If Windows 7 AutoPlay launches, ignore and close it. To hide the XP Mode toolbar at the top of the screen click the pin icon once. To make it reappear move your mouse to the very top of the screen.

2. First time only: the USB Drive needs to be mapped from a virtual Network Drive to a device Drive letter. Open Map Network Drive in My Computer Tools, enter Drive E and Folder \\tsclient\E (or whatever letter you noted in step 1, or choose Browse Microsoft Terminal Services). Check Reconnect at logon and you won't need to do this again. If you might be using more than one USB drive at a time or will Disable XP Mode Integration Features (below) then do the same for F and G now even though nothing may be currently attached there.

3. Launching DisplayMate: in either My Computer or Windows Explorer double click the icon with the Drive letter DisplayMate is on like E: (not the E Network Drive) and DisplayMate will launch and run exactly as in 32-bit systems. If Integration Features are Disabled (below) then DisplayMate will instead launch automatically.

4. When you are done, Safely Remove the DisplayMate USB Drive from Windows 7 in the usual way. If you have Disabled Integration Features (below) then Safely Remove it from XP Mode in the usual way. Note this step is not always necessary but a good idea unless you are sure that it isn't.

Additional Functions and Tweaks

Adding a Shortcut to launch DisplayMate directly from the Windows 7 Desktop:
This will automate all of the above steps except the final Safely Remove step. Right click the XP Mode Start button, select Explore All Users, then Programs. Create a shortcut for DisplayMate by right clicking a blank area and selecting New then Shortcut. Click Browse, then My Computer then Drive E: (or whatever drive letter DisplayMate is on), then DM_FILES.USB, then DMW_USB.EXE and OK. Then hit Next, enter a descriptive name like DisplayMate USB and Finish. Shut down XP Mode, click the Windows 7 Start button, then All Programs, Windows Virtual PC, Windows XP Mode Applications, then drag the DisplayMate shortcut to the Desktop. You can now launch DisplayMate from the Windows 7 Desktop - make sure that the USB Drive is plugged in. Sometimes XP Mode fails with an error on the first try, simply do it second time after a few second pause.

Switching to 24-bit color:
XP Mode defaults to 16-bit color, which is satisfactory in many cases. To switch to 24-bit color, close DisplayMate and its Explorer Window, exit full screen using the XP Mode toolbar. From the XP Mode Menu select Tools and Disable Integration Features. Then open the Control Panel, select Display, then Settings, then 32-bit Color Quality and OK - Windows will remember this setting whenever Integration is Disabled. From the XP Mode Menu select USB and click Attach USB Mass Storage Device. DisplayMate should automatically launch - if not, then manually launch it from My Computer or Windows Explorer. Information on permanently setting the default color depth to 32-bits is available on the web.

Circles are oval instead of round:
XP Mode has set the display driver Screen Aspect Ratio to 4:3 instead of your actual screen size. DisplayMate has a Square Pixels option that corrects this by ignoring the Windows supplied value. To implement this add "S" to the DisplayMate command line "DMW_USB.EXE S" on any Windows Shortcut that launches DisplayMate. If you don't know how to modify or create a Windows Shortcut see below. The Multimedia Editions can also do this from the Special Options Menu.

Full Screen is reduced by 2 Lines:
In some cases XP Mode reduces the maximum usable screen area by 2 lines - the lines are still there but Windows won't allow DisplayMate to use them. In most cases 2 less visible lines is not significant. To regain those 2 lines launch DisplayMate from the Windows 7 Desktop.

Auto Launching DisplayMate when Integration Features are Disabled:
In XP Mode if Integration Features are Disabled then DisplayMate will launch automatically when you Attach the USB Drive to XP Mode as described above.

You get "This is an Invalid Copy of DisplayMate" Message:
On some systems and versions of DisplayMate you may get this message. To correct it Disable Integration Features as described above.

How to create a Shortcut for DisplayMate:
To create a Windows Shortcut in any Folder or on the Windows Desktop right click on a blank area and select New then Shortcut. Click Browse, then My Computer and locate the DisplayMate USB Drive E: (or whatever drive letter DisplayMate is on), then DM_FILES.USB, then DMW_USB.EXE and OK. Then hit Next, enter a descriptive name like DisplayMate USB and Finish.

How to modify a Windows Shortcut:
Right click on the Shortcut and select Properties. You can change the drive letter or Command Line under Target and Start in. If the Shortcut is Read-only, switch to the General Tab and remove the check from Read-only.
