Question [Q] [HELP!] HTC One M8 T-Mobile to GPE zoe not working/installing

Hi I've been playing with my newly acquired HTC M8 bought from TMobile and a couple days ago I flashed the GPE on it, I really like the GPE rom, but I don't want to lose the Zoe camera, I found a thread here that said it could be installed in a couple of differentways, I tried installing the APK directly from a file explorer and all I get is an error, I also tried to put the file in the sys-apps folder, again no luck and finally tried to install the .zip file from TWRP and getting an error.

Has anybody been able to install zoe on the M8 GSM converted to GPE?

Thanks in advance.
