Win10 ‘Access violation’ after installing NoMachine

[ninalin]

Hello everyone,

I have just installed the latest NoMachine for Windows 9.0.188_11 yesterday. After rebooting, I still cannot successfully see the NoMachine GUI, even though I can find the PID of NoMachine services including:

NoMachine Device Server

NoMachine Node Process

NoMachine NX Server

NoMachine Server Process

 

Here’re the error messages in trace.log (also attached)

Module: C:\Program Files\NoMachine\bin\nxplayer.bin pid 8032

Thread: 12652 exception 0xc0000005, ‘Access violation’

In: C:\WINDOWS\System32\KERNEL32.DLL at 0xb4fd2199

Error: Invalid write to address 0x16

#0  0x00000000b4fd2199 KERNEL32.DLL(lstrcpyW)

#1  0x000000008000e953 wintab32.dll

 

My Windows version:  22H2 (OS Build 19045.5965)

I studied other posts on this forum and have tried the following, but none of them work:

– disable firewall and antivirus

– add NoMachine to rules (the processes are in the whitelist from the beginning)

– update Visual C++ redistributable

– update wintab32.dll as suggested in https://support.huion.com/en/support/solutions/articles/44002332146-issues-with-wintab32-dll-file

– install the previous version 8.15.3

– try in Safe Mode (still cannot see the GUI)

I have attached the logs and the .nx folder.  on.

 

Many thanks!

Nina

Hi! I’m sorry for the delay, I was sure your post was handled but… can I say my brain is burning because it’s too hot? 😀

By the way, kidding aside, your problem seems to be caused by a Wacom driver, however I didn’t understand if you started reproducing it after updating to v9 or if also the previous installed version was affected. It should definitely be a Wacom problem so any NoMachine version should make no difference. Could you temporarily uninstall it and confirm that the NoMachine client starts correctly, please?
