13.1 installed 32bit system despite 64bit cpu

after installing 13.1 on a thinkpad x240 which has a 64bit cpu (i7-4600), I noticed that a 32-bit system had been installed.

shouldn’t the installer have detected the 64-bit cpu automatically?

is it possible to select installation of x86_64?

No.
There’s a 32bit Installation CD/DVD and a 64bit one.

is it possible to select installation of x86_64?

Download the 64bit installation disc and install fresh.
You could try to choose “Upgrade an existing installation” to switch the 32bit system to 64bit, but if it is a fresh installation anyway you can just as well install new to avoid any problems.

Btw, you do not have to install a 64bit system on your 64bit hardware.
A 32bit system works just fine on a 64bit CPU.

See here for the differences between 32bit and 64bit systems:
https://en.wikipedia.org/wiki/64-bit_computing#32-bit_vs_64-bit

But note that on a 32bit Linux you are not limited to 3 or 4 GB RAM.
Linux supports up to 64GB RAM even on a 32bit system via the use of PAE.

That’s right.

Although there have been, ocassionally, a biarch DVD that did detect the
architecture and change the installation appropriately. But it was not
available for download, only for purchase, and it was about double size.

I would not recommend that upgrade unless the user is experienced.

Check more carefully, a 64-bit system does install a partial 32-bit
subsystem.

Just check the output of “uname -a”.
