What is the “This script was generated with an outdated DFE engine” in load runner

“This script was generated with an outdated DFE engine” in load runner

Fatal Error -26000: This script was generated with an outdated DFE engine, regenerate the script in order to successfully replay the DFE steps.

Warning: Extension lrwreplaymain.dll reports error -1 on call to function ExtPerProcessInitialize

Error: Thread Context: Call to service of the driver failed, reason – thread context wasn’t initialized on this thread.


This error occurs because the script is being replayed with a version of the DFE engine newer than the one it was generated by. It usually happens if new patches are installed after the script was recorded.

There are 2 possible workarounds for this issue

Method 1:
Do the following 3 steps to fix the issue:

1. Navigate to the script folder
2. Delete the folder named DfeConfig
3. Regenerate the script in VuGen.

Method 2:

1. Open script folder
2. Delete DfeConfig folder
3. Replay script


any method works perfectly.
