Package for older ARMv7 iOS devices in 4.17

I’m making an educational game to install in some schools, however they only got the iPad 2 and iPad Mini Gen 1 models.

Any way to force packaging on 4.17 for these devices that are not 64-bit?
I already made so much content using 4.17 and would like to avoid having to rewrite on 4.15 for example, where I can package choosing ARMv7.

Also it fails at 40% when using iPhonePackager, presumably because of the incompatibility for armv7.

Thanks in advance.

Mike.

have you solved this problem?
I also want to know how to package iOS ipa for armv7 with UE4.18
And I don’t know why the app crashed when it install on ipad mini4 which is A8 achitecture?
