    Looks like the GRASS7 folder C:/PROGRA~1 is suggesting a 32-bit installation folder (Program Files (x86))? Your QGIS might be 64-bit version. – Kazuhito Nov 3 '18 at 10:50
  • Hi, the QGIS it´s a 64 bit version. I am using Windows 10 Pro 64 bits. – Vitor Pina Silva Nov 3 '18 at 15:53
  • Then you may have another GRASS 7 under C:\Program Files\QGIS 2.18\apps\grass\grass-7.4.1. Could you set it up as your GRASS7 Folder and see what happens. – Kazuhito Nov 3 '18 at 16:01

This problem it´s solved. i realize that anti-virus had block grass and several components. So i have unblocked them, and have re-installed QGIS 2.12 first, then QGIS 2.18. Then copy msys as well as grass 6 folders in apps in QGIS 2.12 to apps in QGIS 2.18. And now both run perfect grass 6 in QGIS 2.12 and grass 7 in the QGIS 2.18

Many thanks for your time and help.
