I had apps foreclosing as well on my first tries. I first installed Android -x86 rc2 and did not erase the whole folder created on the drive where i installed it before installing cm 14.1. The next tries, I made sure that I deleted first the folder, in my case, created on drive: C where my windows is installed. Also, delete the Grub folder if you installed it before installing cm14. Now, i'm back to -x86 rc2. I installed Grub, gave it 16GB and made System R/W.
