I applied for the Non-Commercial 64-bit edition of kdb+ about one and half months ago. I just started to use it. I put the license file in the `QHOME` folder as required and run the q file. These is still the license error.

What is your QHOME variable set to?

C:Users\>echo %QHOME%

C:q

You may need to set it to the correct folder location. It is also helpful to add q to your PATH while you are at it:

C:Users\>setx QHOME “D:kDBw64”

C:Users\>setx PATH “%PATH%;D:kDBw64w64”

Full installation instructions here: [https://code.kx.com/q/learn/install](https://code.kx.com/q/learn/install")

(Being pedantic, you can also remove the top level w64 folder in order to neaten up the environmental variables mentioned.)

for default installation, you should put the kc.lic file in your $HOME/q directory :

baichen@MacProM1:~/q$ ls

kc.lic m64/ q.k
