How to use DivX software on Windows XP SP2
Some of Div X products may not work with Microsoft Windows XP Service Pack 2 when a feature called Data Execution Prevention (DEP) is enabled. DEP is enabled by default in Service Pack 2. Typical symptoms include the following:
DivX
The DivX codec may not appear in the list of available video compressors
DivX Pro
The DivX Pro codec may not appear in the list of available video compressors
Dr DivX
The Dr DivX installer may exit before installation is completed
The DivX Pro codec may not appear in the list of available video compressors
Right-clicking files in Windows Explorer may cause Explorer to crash
Data Execution Prevention may also cause other software on your system that has not been specifically designed for SP2 compatibility to fail. For more information on DEP, please read more about Windows XP Service Pack 2 on MSDN.
Disabling DEP in Windows XP Service Pack 2
A short-term solution to DEP incompatibility is to disable DEP. Disabling DEP is a security risk, and will increase the vulnerability of your computer to certain types of attacks, but no more so than was possible under Windows XP Service Pack 1, which did not include the DEP feature.
If you choose to disable DEP, we recommend that you try to update all your software and drivers to Windows XP SP2-compatible versions as soon as they are released, and then re-enable the DEP feature. DivXNetworks will be releasing SP2-compatible versions of all affected products shortly. We also recommend the use of up-to-date anti-virus and firewall software at all times.
How to disable DEP
To disable DEP, perform the following actions:
Click Start -> Run
Enter Notepad %SYSTEMDRIVE%\Boot.ini
Under [operating systems] replace the parameter /NoExecute=xxxxx with /Execute
Save the Boot.ini file
Restart your computer
IMPORTANT: Save a copy of your original Boot.ini file as a backup before you make changes!
