Windows Installer gets terminated by Data Execution Prevention

Question

I'm trying to install something, and all of a sudden Windows' DEP kills Windows Installer. This has happened to me before. Is there a fix for this I'm not aware of? I'm on XP.

Answer 1

One thing to try is to see if DEP is causing the problem, so you need to turn it off.

1. Click Start
2. Select Control Panel
3. Select System
4. Click the Advanced tab
5. In the Performance region select Settings
6. Click the Data Execute tab in the dialog box that opens
7. Select Turn on DEP for all programs and services except for those I select
8. Click Add.
9. The open dialog box will open. Browse and select your application.
10. Click Open
11. Click Apply
12. Click Ok
13. Reboot

Answer 2

Make sure you've got the latest version of Windows Installer first.

However, you may find that the package you're attempting to install is incompatible with DEP - some custom actions or third party extensions are. In which case you'll need to follow Systech's suggestion, or get an updated version of the package.
