Some of our clients have a problem we can not reproduce here inhouse: Out software uses MS-Word for producing form letter. Since some of our clients use Office 2013, this function won't work anymore.
We tried to reproduce this and detect that on the affected systems Word won't start from command line. Starting via the link in the startmenu works. It also works to start Excel from command line.
Does anyone have an idea what the problem is and how to solve it?
We found the solution: Our software still uses old 8.3 filenames - also long filenames are replaced with short ones. And it seems that Office 2013 don't like them anymore.
