I just downloaded the KX Developer and Installed it. It works to do the computation, but it doesn’t work to print messages.   In KX Developer, if I simply run “show 123”, I will have the error “cannot write to handle 1. OS reports: the parameter is incorrect”. Any ideas? My version is “KX Developer 1.5.4”.   ---

I did a test: 1. Downloaded `developer-1.5.4-windows.zip` 2. Extracted and ran `install.bat` 3. Opened the install folder and ran `config\config.bat` 4. Ran `q launcher.q_` 5. Opened my browser and ran `show 123` using `Ctrl+D` Works as expected: Q version:   q)(.z.K;.z.k) 4f 2021.10.01     1. What OS are you on? 2. Are you following the same steps as above or different? 3. Does the issue remain after you restart Developer’s underlying q process? ---

Thanks for your reply. 1. I’m using Windows 11 version 22H2 (OS build 22621.1555) 2. Yes, I used the 5 steps as mentioned by you and then I saw the error I mentioned. But I run ` **C:\q\w64\w64\q.exe C:\developer\launcher.q\_** ` instead of ` **q C:\developer\launcher.q\_** ` because I have 32-bit q and 64-bit q so I need to specify a 64-bit `q.exe` 3. Yes I tried restarting developer/browser/laptop and still have this problem ---

I didn’t modify **q.k**. Meanwhile, I don’t have a **q.q** file. When I downloaded the  **w64.zip** file from the url provided by the free-trial-email, after unzipping the only available files I saw are **q.exe** and **q.k** , and there is no **q.q**. Where is no problem for me to load workspace. If I run **.z** and **.Q** etc., there is no error. It seems that the handle **1i** is not connected to my console. If I run **1i"123"** , theorectically it should output **123** , but at my KX Developer it just give me the same error “cannot write to handle 1. OS reports: the parameter is incorrect”. ---

I have encountered the same problem as you, how did you solve it, how can I use show in developer? ---

Hi, I haven’t solved the problem. Currently, I’m using a workaround as below: 1. Open another q-session in cmd, and then listen to a port using  **\p** , say port 9001 2. At KX Developer, create handle **h1** which connect to 9001 using  **h1:hopen`::9001** 3. At KX Developer, if you run  **h1 “show 2+2”** , you will see 4 at the q-session This workaround is not very ideal, but still a bit helpful while debugging ---
