The Microsoft support simply does not know anything on this, but want to sell me an 300€ Tech.Ticket. Click on 'Microsoft' and search for 'Office' under it. From the left side panel, click on 'HKEYLOCALMACHINE' followed by 'Software'. Type 'Regedit' and hit Enter to launch the Registry Edit window. I hope somebody had similar issues, and knows a solution. Click on Start and type 'Run' to launch the run window. The trial itself is "Professional Plus", but can I activate it with a "Professional" license? Since "Professional Plus" only seems available via volume licensing, which we still do not want.

So my question is: Which license key do I need to activate the trial.

Since we do not want volume licenses, I did a little research, and found out that some people that need to change the path of the install location, installed the trial version of office which comes with the msi Installer, and then activated it. After hours with the Microsoft support, we found out that the msi Installer for Office 2013 we need for this, is only shipped with volume licenses. So when we tried office 2013 and therefore simply bought an single "Home and Business" license, we soon recognized that with the (Irony on) wonderful (Irony off) Click-to-Run Installer we can not achieve this.

Due to some third-party software, we have to install office in the 32 bit Version, but it must not be in a path with "(" or ")" in it (This is an issue with an oracle client, and we definitely can not change here).
