Bugs when using two versions of matlab on the same system

Hello,

I've been using R2015b for some time and decided to install R2018b as well to work on some code a colleague had made. Since I have lots of packages related to speedgoat etc. in my R2015b installation I decided to keep it instead of just upgrading to R2018b. When I went back to work on some rtw stuff on R2015B I noted that my default C compiler had changed from SDK 7.1 to MinGW. I have had both installed since before the update but only used SDK 7.1.

• Is this a known issue?
• Are there any other issues related to having two matlab installs in parallelle?

I don't know/can't remember where it is defined and what is covered, but as far as I am aware some preferences for Matlab are on a user basis rather than a version basis and so would affect every version you have installed. Usually this is a good thing, I guess sometimes it is a bad thing though too.
