CCS: Can't install CCS 7.2

Tool/software: Code Composer Studio

I'm about to start some new developments and decided to remove old CCS and intall fresh.

But I've been facing many problems while installing and I didn't manage to finish successfully. It either stalls while unzipping. or fails to find an eclipse executable (?) or some varieties of error messages. I've tried on Windows 10 (online and offline) and on Ubuntu (online).

What might I be doing wrong?

EDIT:

The last try stalled (around 10 minutes without any progress) on "Unzipping C:/Users/Caio/AppData/Local/Temp/ccs_79621e3b-deb9-4e13-5c54-a2c51a71f4eb/jre_root_1.8.0.122" step and when I cancelled gave me the following message:

I was running the version 7.2 offline windows installer from http://processors.wiki.ti.com/index.php/Download_CCS#Code_Composer_Studio_Version_7_Downloads

EDIT 2:

Tried once again, without cleaning the .../ti folder. It recognised the earlier install attempt but gave me the "Can't find eclipse executable". The log files are annexed.
