CM12 Beta issues topic

Hi i started to ask questions in the actual thread but someone else was told off for asking questions and directed to Q&A so here goes.

i installed the ROM and then found after installing the full gapps that although it installed the gapps zip successfully when i booted, there were apps missing such as play store and play services. someone said that it was due to the size of the install being too large and to install the mini or micro package.

so, after downloading both, i cant install either. it says 'no changes were made to your device, installer will exit' then after a few more words 'e:error in' and it shows the path to the zip with (status 1) after it. tgen lastly E: Installation aborted.

any ideas what i am doing wrong?

cheers
