Problem
When trying to run Substruct Utiilities (substruct.exe) over the network for the first time, you may receive an error:

The application failed to initialize properly (oxc0000135). Click on OK to terminate the application.

1. Open Control Panel.
2. Open Administrative Tools.

4. Expand Runtime Security Policy.
5. Expand Machine.
6. Expand Code Groups.
7. Right-click on All_Code and click Properties.
8. Click the Permission Set tab.
9. Change the Permission Set drop down to “Full Trust”.
10. Click OK to save this change.
