What are "Compatibility Mode" settings and how can they affect my programs?
Compatibility Mode is a set of tools that will add small pieces of code to older programs to help them run on newer versions of Windows. In Windows Vista, 7, and 8 an extra tool, Run As Administrator, was added to help more complex programs work with the User Account Control security feature.
If a RealNetworks application is running with Compatibility Mode settings turned on, it can experience various different errors or unexpected behaviors. On Windows XP, these programs should be used without any Compatibility Mode settings enabled. On Windows Vista, 7 and 8, it is strongly recommended that these applications use the Run As Administrator option. No other Compatibility Mode options should be enabled.
To check these applications for Compatibility Mode settings:
1. Click the Windows Start button in the bottom left of your computer screen.
2. Right-click on the icon for the program or browser.
3. Select Properties.
4. Go to the Compatibility tab.
5. Uncheck any boxes that are checked (VISTA/7/8 USERS: leaving "Run As Administrator" checked is fine).
6. Click Apply.
7. Click OK.
