I am not so happy with my order from Softwareking: I had ordered Office 2016 Pro. I had asked the support beforehand "whether the Office software is installed with MSI or C2R Installer".
The answer was: "this is the click-to-run version [C2R]".
Unfortunately, I only got a download link to the ISO file for an MS installer, and the licence key is also only a volume licence for MSI. Because I have other Microsoft software on my computer that is installed with C2R, I cannot use the product from Softwareking.
After I had emailed that I would make use of my right of withdrawal, I hear silence.
The screenshot shows that it is not possible to install MS Office 2016 with MSI from Softwareking on my Laptop that has already installed MS Project which was installed with C2R.
