If you’re new to Windows Vista, you may have found out the hard way that you’re no longer able to install some of your old software. This is a common problem with Vista, but it can be easily fixed by trying these two simple solutions.
If the program is installed, but you’re unable to use it, the easiest fix would be to try Vista’s built-in compatibility wizard. Click your Start button in the bottom left corner of your screen, then type C:Program Files in the search box and click "Enter" on your keyboard. Locate your program in this list by double-clicking on name of folder, such as Microsoft Games, then by finding the appropriate .exe program.
Note: You can also click Start and find the program in your "All Programs" list, then continue with instructions.
Once you’ve found the correct file (Example: Solitaire.exe), right-click on its name and choose Properties. A new box will open with four tabs at the top. Beneath Compatibility mode, check the box to "Run this program in compatibility mode for Windows XP (Service Pack 2)." You may have to select Windows XP in the drop-down menu.
Click OK and try your program again. If it works, congratulations. If not, try Step 2.
Click your Start button again, then right-click on "Computer" and choose Properties. This will open your System folder. From here, you’ll see a list of "Tasks" in the top left-hand column. Click "Advanced system settings" (click to continue if a box prompts you for permission to go on), then beneath Performance, click "Settings." In the box that pops up, click the tab at top for "Data Execution Prevention" and select the second option to "Turn on DEP for all programs and services except those I select."
Add your old software to the list by clicking "Add" and locating the program’s .exe file in the drop-down menu at the top.
You may have to restart your computer for the new settings to go into effect, then try it again. Unless the program is a thumbnail creator like Media Resizer, it should work now.
Pass on your new knowledge to all of your Vista friends. They will thank you for it.
