I am not able to save or at least preview my new crystal reports in SAP Business One. I hope this is just a installation issue, but hard to find out how to fix it.
If you have the same issue, at least you can test your reports using the "Tools / Preview External Crystal Reports File" menu.
Funny workaround, but at least it works, and it looks it works even faster than using the preview function under the add-in menu.
