An unexpected error occured - InvalidCastException

I have installed LR 12.55 on a Win 7 machine, and get the following error when trying to start recording:

An unexpected error has occured.

Source: HP.LR.VuGen.StartRecordingDialog
Target Method: Void RealLocalProxySettings(HP.LR.VuGen.RecorderBackEnd.RecordingInfo)
Message: Unable to cast object of type 'System.Int32' to type 'System.Byte[]'.

Does someone have a solution?

 

  • Hi

    Which protocol are you trying to record in?

    if web - are you recording in local proxy mode or "normal" mode? if in Local proxy, can you modify back to "normal" and see if this recreates? does this happen in each recoding attempt? does this happen on other machines as well?

    thanks,

    Lior

  • Hi, COuld you please provide a screenshot, and if applicable, also copy the "inner excetipn" infromatiion to us? Thanks.

  • Hi,

    We are recording on the Webprotocol. It is the same on both modes, and it does only happen on some machines. We suspect it has something to do with permissions, but we need anything more specific to report.

    The funny thing is that webrecording works when using mulitprotocol (Citrix HTTP)!

  • There are 0 inner exceptions.

    Here are some screen shots:

  • Hi,

    I've got he same issue right now.

    Would it be wrong privilege during installation ?

  • I now have this same problem.  Was there a fix created?

  • I got this error when trying to record an SSO login script.  I ran VUGen using "Run As" a test user account, instead of my normal AD credentials - hoping that I could record IE while using one of our test userids.  (I can record this application using my own AD credentials, but my personal account is set up with Multi-factor authentication, which I do NOT want to script).

    When I am running VUGen 12.55 using this other user account I also get this error "Unable to cast object of type 'System.Int32' to type 'System.Byte[]'." 

    I think what this error means is that VUGen is encountering an issue (improperly handled in its error logic) while trying to configuring a Proxy for recording - due to a permissions issue in the registry (ReadLocalProxySettings).
