TWRP Cyanogenmod 12.1 gapps fail install

[mykimike25]

Hi

So I've installed TWRP and rooted my Nexus 9. I've installed Cyanogenmod 12.1 nightlies with no problem either. But I can't install gapps. If fails on install in TWRP.

Installing '/sdcard/Download/vendor_google-arm64.zip'...
Checking for MD5 file...
Skipping MD5 check: no MD5 file found
Error flashing zip '/sdcard/Download/vendor_google-arm64.zip'

. I have downloaded and tried all 3 types offered at Cyanogenmod with no luck. I have the latest TWRP 2.8.7.0 but I can't figure out how to install gapps.

Any ideas?

I ended up having to download the 2015-06-02 from the GApps GitHub repo to get mine to work after facing the same issue.
Can't post the link but file name is:
gapps-5.1-2015-06-02-15-19.zip
