Client does not start on Windows 10 Pro

[mscher]

Hello,

I have installed ‘nomachine 8.10.1_1’ on my Windows 10 Pro laptop but when I use the link to run “C:\Program Files\NoMachine\bin\nxplayer.exe” nothing happens in the GUI.

The laptop is running Trend Micro Security Agent which is managed by the organization I belong to. I have installed other software without issues, but I am wondering if this could be blocking NoMachine.

I did install the latest version (twice!) and rebooted the machine.

Any help/suggestions is appreciated.

Can you check if you’ve a file called nxtrace.log in %PROGRAMDATA%\NoMachine\var\log and send it to forum[at]nomachine[dot]com?
If this file doesn’t exist, after you try to start the Player check if there is a NoMachine Player process running in your task manager.

Thanks, the log is there.  It is filled with this message:

The Task Manager has entries for:

NoMachine Device Server

NoMachine Node Process

NoMachine NX Server

NoMachine Server Process

NoMachine Tray Monitor

[Tor]

That TmUmEvt64.dll crashing is related to Trend Micro (AMSP UMH module), but the stack you pasted is about nxserver binary, so from the info you supplied I can’t confirm Trend Micro is also having problems with the NoMachine client.
Do you have a way to add a temporary exception for nxplayer.bin and nxplayer.exe, or a way to check a log of Trend Micro to look for messages related to NoMachine binaries?

Tor,

Thanks for your help. Unfortunately the Trend Micro app is managed by the company IT department, so I am afraid I can’t disable it. I will contact them and see if there is anything they can do.

Thanks again.
