I think the specified file is not existent or not readable by the LAPI application (e.g. insufficient permissions).Then it may happen that the CreateVersion function is called without the required "FileAttributes" parameter (which is constructed internally by the LAPI client library) and then you will see exactly that error.[Btw: I guessed that you use a LES version <= 9.5, correct? However, nearly the same error will occurr also with later versions.]

Hi,You could get the error when you are trying to add a document that is not present in the local file system or from wherever you are trying to add.I can explain a bit more below.I guess you have a piece of code as below.doc.CreateVersion(volumeID, objectID, "c:\\temp\\tlistd.txt", versionInfo) != 0)In the above code if the name of the file that you are trying to upload, if not present in the specified directory. In this case c:\temp\tlistd.txt has to be present in that location.And do not forget to put the "\\" there.Hope this helps.Please let me know if this would solve your issue.Thanks,Sunu Easow

Hello Ajay,As others have mentioned, that message will be thrown if the referenced file cannot be opened.The reason why the odd error message is received is due to a bug that allows the incomplete request to make its way to the Livelink server (which the server then mishandles).For future reference, I have entered a bug for this issue with the reference number #LPO-557.Thank you for bringing this to our attention.
