Fatal Error while replaying script

Jump to solution

I encountered a problem that makes it impossible for me to use LoadRunner. Whenever I'm trying to replay any script (whether recorded by me or downloaded sample script for WebTours tutorial so that I'm sure it's not corrupted in any way) in Virtual User Generator I immediately get this error:

Fatal Error -26000: xfiLrwSrvNetGlobalInit failed [MsgId: MERR-26000]
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.

The same error (Fatal Error -26000: xfiLrwSrvNetGlobalInit failed [MsgId: MERR-26000]) also happens when I try to run a scenario in Controller.

I tried probably everything that I could think of to resolve the issue: reinstalling LR, installing previous version, disabling firewall & security on my computer, reinstalling MS Visual C++ Redistributables 2015, checking for Windows updates. It was all in vain and I don't have any more ideas as I don't understand what the real problem might be. However, when I installed LR on my home computer with the same OS, it worked perfectly well, so there's probably nothing wrong with installation files or the way I install the program.

I'm working on Windows 10 Pro (vesion 1803).

I would appreciate any help as I've been stuck with it for a long time now.

Reinstalling Windows resolved the issue but I still have no idea what went wrong in the first place and thus how to prevent the same problem from reoccuring in the future.

Hi,

I am facing same issue and still no solution. I am trying to replay with LoadRunner in Windows 10 Pro but I get exactly the same errors as mentioned above.

 

I cannot format and reinstall Windows at this time, so I wouldn't say that this issue is solved in this way. I have tried with different versions of LR, 12.60, 12.63 and the new LR2020 but no success.

 

Any hint to solve this? Thank you in advance

@igorrh, the user @hubert19 was just lucky that the error went away after reinstalling. I experienced the same error and issued a support request to Micro Focus. While running some traces for MF, I happen to find the cause. It has to do with a Beta language setting in W10. When you disable this setting all works again.

This is what you need to do:

Navigate: Start -> Settings -> 'Time&Language' -> Language -> 'Related settings' -> 'Administrative language settings' -> 'Change system locale...'

Uncheck: 'Beta: Use Unicode UTF-8 for worldwide language support'

Press: OK

Reboot your system
