Tip — Other Tools: Toad Installation Issue

Just recently, we installed the free version of Toad on a development VMWare server. After logging in, we received two error messages:

Access violation at address 00000000. Write of address 00000000.


Error loading SPServer.

I found the fix for these error messages at:

Basically, you must turn off Data Execution Prevention for Toad.

  • Go to the System Properties:
    Control Panel, System or Start Key+Pause/Break Key
  • On the Advanced tab, click the Settings under Performance
  • On the Performance Options, go to the Data Execution Prevention tab
  • You should see selected: “Turn on DEP for all Programs and Services except those I select”
  • Click the Add button, and browse to the Toad executable.
    Probably: c:\Program Files\Quest Software\Toad for Oracle FREEWARE\Toad.exe
  • Choose Ok/Apply for all the Windows and try to run Toad again.
