I Have a new problem, that I can´t fix by my self.
We use OpenOffice in our company as Office-Programm. On new PC´s where we install GW18, and OpenOffice, it is not possible to send dokument as mail out of the OpenOffice. So the user must save the dokument to disk and send them from there. I tried LibreOffice and it works.
But Send an Dokument or an other file with an rightclick to mail or an mailto-link at the internet works great, the problem is OO.
On my one PC there isn´t this problem. But I was upgrade the GW2012-Client to GW18.0.1. So I tried to set the new PC to the same and deinstalled GW18. After an reboot I installed GW2012-Client, the test with OO works an GW18 will open wehen I click on "Dokument to Mail", then I Upgrade to GW18-Client and it still works. but it can´t be the solution that I must install GW2012 first.
Maybe there is an workaround that I have not found for now
