How to change the bitness of the php version to x64?

Question

open server

Hello! I have a laptop with licensed windows 10 x64 installed. I installed a clean site on wordpress on the local OpenServer x64 , I want to import data to it through the All in one wp migration plugin , which take up more than 2GB and I get this error:

Unable to import Your PHP is 32-bit. In order to import your file, please change your PHP version to 64-bit and try again.

What can be done?
P.s. I tried to do everything the same through Bitnami wampstack-7.1.23-1 - everything is the same

Answer 1

Just select the 64-bit version of Apache + PHP in the Open Server settings.
