Thank you for your prompt help with this issue.
It is really a mess of microsoft that such an important runtime library used by hundreds of applications is not installed by default.
Normally I would not have run into that problem because most times Visual Studio is installed on my pc's, this way all runtimes are also installed.
One solution would be to provide the user with a Readme or some other kind of installation note with a link to the necessary runtimes, but this is surely not very satisfying. For my part I like your approach, that the zeus installer only provides the core zeus files and not any other runtimes or other files. This way the installer is kept small and simple.
One other, different question. From some other text editors I know the following, very nice feature: The find/search dialog has a button/checkbox to allow the user to highlight all occurrences of the searched word/expression with a certain color.
Don't get me wrong here: the find function still only searches for the next occurence, but in addition all occurrences get highlighted in some flashy color.
Here an example for the feature I'm looking for:

.
In the example it was searched for "type 3". The first occurence that is the result of the find operation is shown in some kind of olive color, all other occurences are shown in a flashy green. This way one can easily detect further occurences of the search string when scrolling down the document....
Does Zeus provide this function? Or is this kind of feature already on your todo list/roadmap?
Best regards,
Christian
