Thanks for the suggestion, but I am still facing the issue.
I read in an open form,
To avoid a situation in which an application asks for NTLM authentication while recording and replaying, one has to specify the application as a trusted NTLM resource. To make that, follow these steps.
Open the file “user.js” located in “%lr_path%\dat\LrWeb2MasterProfile”. Locate the preference setting “network.automatic-ntlm-auth.trusted.uris”. Specify the URL of the trusted resource as the value of this setting. Save the file “user.js”
I made the changes, but the thing is... after doing the changes I am able to run in my vugen machine 11.04 successfully. But the same changes done on machine 11.00 is throwing the below error as that of performance center error. I also made changes in lG machine but still facing the same error
