If you instrument certain services or applications that the operating system can launch, you should add the Purify cache directory to your system Path environment variable. (Note: It is important to add these directories to your system Path environment variable, not just your user Path environment variable.)
To add this variable to the system Path environment variable:
1. Double-click the System icon in the Control Panel.
2. If you are using Windows 2000 or higher, click the Advanced tab, Environment Variables.... If you are using Windows NT, click the Environment tab.
3. Append the Purify cache directory to Path in System Variables, click Set, and then click OK.
4. Reboot your machine so the system uses the new value.
