I tried multiple ways on my MacBook Pro and my VMFusion (whose environment supposedly is windows 11) still the error message ‘License error: k4.lic’ persists.

My folder structure is as below: (The first is that on Mac, the second&third is that on VMFusion).

P.S. I would prefer KDB+ be installed on my Mac instead of on my VMFusion, if possible. But I would also really appreciate it if I can solve the problem on my VMFusion.

Copying my reply from under your request on a different thread:

[Re: Getting License error - KX Community - 13316](https://community.kx.com/t5/kdb-and-q/Getting-License-error/m-p/15523#M12156")

First image looks fine for QHOME=/voiddump/q/m64

&nbsp;

More traditional structure would be to not have that extra level of m64

.i.e

- voiddump/q/kc.lic
- voiddump/q/q.k
- voiddump/q/m64/q

In that case you'd use QHOME=/voiddump/q

Your Windows VM screenshots are incorrect:

You have `q/w64/w64/q` it should be `q/w64/q`

I changed the QHOME to /voiddump/q and it works! Thank you so much!
