When installed correctly, WinDbg* detects the extension automatically. If WinDbg* does not detect and load the extension automatically or if the extension was installed manually, perform one of the following actions:
Place ptext32.dll and ptext64.dll in a directory where WinDbg* searches for extensions by default. These are usually all directories in the PATH environment variable and some others. To display all searched directories, use the .extpath command in WinDbg*.
Add the path to ptext32.dll and ptext64.dll to the _NT_DEBUGGER_EXTENSION_PATH environment variable. Create that variable, if it doesn’t exist.
Use the .extpath+ <directory> command in WinDbg* to add the directory containing ptext32.dll and ptext64.dll to the search path.
This setting only applies to the current debug session and is not saved when WinDbg* is closed.
Usually, WinDbg* loads detected extensions automatically. If this fails, you can load the extension manually. Use the .load ptext32 or .load ptext64 command in WinDbg*, depending on whether you are using a 32-bit or 64-bit version of WinDbg*.
