Strange SoftMaker behaviour

[Léon]

Not very long ago I re-installed SoftMaker Free Office. Since then a few times the question came if I want to download a new Service Pack. Yes, of course!

The next thing was: “No valid products found. Please repair the installation”.

Also, as soon as I want to save a document, in .docx (my standard format), the question comes if I want to use the most recent compatibility modus with Microsoft Word, something like that. Yes, of course!

After changing the spelling control from Dutch to English it just stays Dutch.

Repair also fails. In the download folder there seemingly has to be "a valid SoftMaker Free Office .msi".

When I place the latest SoftMaker Free Office .msi in my download folder, the notification comes that this is not a valid .msi. (Just downloaded it from The SoftMaker website).

How can I go back to a normal SoftMaker behaviour? Re-install the program again?
