Can't install using pkg in 10.7.5

I have just wrapped my application with App Wrapper and created the pkg file. I can install it fine in Mac OS X 10.12.6 but I tried in an older MacBook with 10.7.5 and it throws message “Application … can’t be installed in this computer”.

Minimum OS version set in App Wrapper is 10.7 and I can’t find any log file with more info.

Thanks for any help.
