I solved the problem. I used the solution proposed here: https://community.altair.com/community?id=community_question&sys_id=7dd600fa1b2bd0908017dc61ec4bcbc1
It seems like when I run the installer by right-clicking and running in administrator mode, it is still not meeting sufficient permissions. To resolve this, you must unlock the hidden "true administrator" account and install S32DS and FreeMaster using this account for all users.
To do this, follow these instructions(use method of your choice):

This is the method I used:
1)- Open elevated command prompt (right-click, run as admin)
2)- Type:
net user administrator /active:yes
3)- Log out and switch to Administrator account.
4)-Install S32Ds and FreeMaster. Do not forget to create shortcuts for all users and update S32Ds after installing.
5)- Log out from Administrator account. Log in to main account.
6)-Open elevated command prompt and type:
net user administrator /active:no
7)- Congratulations! Now you can start programming.
Hope this helps someone in the future.
