That error usually happens if the w2w executable file is compiled on a
64 bit operating system, but then it is copied and ran on a 32 bit
operating system [
https://www.dartmouth.edu/~rc/classes/softdev_linux/32-64bit.html ].
You can probably use the Linux 'file' command [
http://superuser.com/questions/791506/how-to-determine-if-a-linux-binary-file-is-32-bit-or-64-bit
] to check if the w2w executable file is 32 bit or 64 bit:
$ cd ~/WIEN2k.14/
$ file w2w
(where $ is a bash terminal)

Dear all,
During the execution of *x w2w* in order to compute the overlap
matrix, it gave me some error shown below.

~/WIEN2k.14/w2w: Exec format error. Wrong Architecture.

I googled this error but got no solutions. Could you help fix this?
Note that, before execution of x w2w, I have used "x lapw1' to compute
the eigenvectors on full k-mesh. The verison of WIEN2k is the latest
one, and the version of Python is 2.7.2.
