I downloaded exe-file “PLCnext Technology tool chain for Windows including Eclipse Add-in, Microsoft Visual Studio Extension for C++ and C#” and I’m trying to install it. But an error message appears: “C:\Users\*********\Downloads\PLCnext_Toolchain_Windows_2022.0.exe, invalid attempt to access a memory address”. How install this toolchain?
This is a known issue with the download that is currently being worked on (sorry).
If it makes a difference, I am also frustrated by the length of time it is taking to fix this issue.
OK thanks! Will wait 
Is this already fixed? I’m facing the same issue under windows 11.
This was fixed, but it appears that the re-launch of our website has broken the installer again. Sorry about that.
Here a link to an installer that should work:
PLCnext_Toolchain_2022.0.exe
I will delete that link when the file on the Phoenix Contact website is fixed.
Hi Martin,
The installer works for me
Is it correct that i’m missing the Visual Studio extention file (vsix) in when using this installer? In an older version of the installer I found the vsix file in the PLCnCLI folder but wouldn’t install under VS2022. Where can I find this?
Is it correct that i’m missing the Visual Studio extention file (vsix) in when using this installer?Yes. With the latest version of the toolchain installer, the Visual Studio extension is added to Visual Studio during the installation process. You can select or de-select this option during the installation. There is no separate vsix file.
The Visual Studio extension currently only works for VS2019. VS2022 support is planned for a future version.
Thanks for the quick response. I’ve installed VS2019. When installing the C# Visual Studio extension Variable I get an error that the wizard has “ended prematurely” (C++ works well but is missing the remote debugger). What I’ve tried is the following: System reboot and complete reinstall of he toolchain.

Windows logbook tells me the following:
Product: PLCnext Technology Development Tools for Visual Studio (v3.3) -- Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: Install_VS_TEMPLATES_COMMUNITY, location: C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\Common7\IDE\VSIXInstaller.exe, command: /skuVersion:16.11.32407.337 /skuName:Community /quiet "C:\Users\JFCDF~1.WIJ\AppData\Local\Temp\Ade.Eclr.VsTemplates.Extension.vsix"
How can I get the remote dubugger installed?
From the path, it looks like VS2017 is also installed?
I know there have been some issues in the past when multiple versions of VS are installed on the same machine. Can you try uninstalling other versions of VS, apart from VS2019?
How can I get the remote dubugger installed?I don’t think that’s part of the Toolchain installation. Have you installed the VS workloads mentioned below?
I removed vs2017 and was able to install the C# extension. Everything works now.
Thanks for the support!
