I'm using the version 4.5.0-238809, I am virtualizing Excel 2007 and when it finishes the process of creation, I run on the server (locally) and it works without problems. When you want to run it from a remote pc with windows xp I get an error saying: "Unable to open" ...
I include here the package.ini and error message to see if I can help.
Thank you very much!
