CSV exports ignore system region delimiter

We are using Adobe Acrobat 11 for small surveys now and then. It's been working alright most of the times, however on a select few users/computers we have experienced some issues now.

The problem surfaces when these users wnats to export the answers into a csv file. Acrobat then ignores our system region settings regarding the list delimiter. All PCs are running x64 Windows 10 Professional. We are based in Switzerland, running our systems on German(Switzerland) region settings, which means the delimiter should be semicolon. Acrobat ignores this, exporting the survey answers comma separated.

This creates problems when the users want to open the csv in Excel, and convert it to an Excel sheet. The funny (or not so fun) part though is, this only happens on about a third of our users, or more accurate, on their PCs. I have signed on with different users on these machines, and the issue remains.

On the same time, if I sign on to a different PC with the same user, one that indeed exports correctly, it does with the "faulty" user aswell. Which leads me to belive the issue is not with the user profiles.

Some more information that might be of help:

- We are in a single 2008 R2 Server Domain

- All Profiles are roaming

- All clients are Win 10 Pro

- Only about 30% of all clients have this issue

- I've uninstalled Acrobat, deleting everything and reinstalled to no avail

I have not found much online from anyone having the same issues we are facing here. If anyone have any clue to wherein the problem lies, it'd be much appreciated. I'm pulling my hair here.
