SP2 and DivX problems and work around

Archived from groups: rec.video.desktop (More info?)

After installing SP2 I was no longer able to right click on a folder
and get a context menu... explorer would crash...after doing some
research I found out that DivX may be the cause...sure enough one I
removed DivX the problem went away...

The folks at DivX are aware and are working on a solution...
The following is taken from the DivX web site and offers a work around
for those that can't wait for the fix:

Some of our 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!
