[WiX-users] ExecXmlFile error 1603

[kaizen__ hotmail.c. <kai...@ho...>]

Hi All,
I'm getting the following error when performing a 'Change' action from my installer (installation itself went fine, no errors thrown).I've read that this is most likely a situation involving the file already being open for read/write (I'm writing to web.config files), and so ExecXmlFile can't access this... however I would have expected that ExecXmlFile would have told me which file this relates to.Is there another issue that might be occurring (based on this error code), or should I perhaps log a bug ticket against the ExecXmlFile CA to include the file name that caused the error code to be thrown?
