IntelliJ idea-2026.1.3 fail open on windows 10
Operating System: Windows 10
Issue Description: Upon downloading and installing the latest version of the IntelliJ IDEA installer, the application fails to launch. Double-clicking the desktop icon produces no response, and running the application as an administrator yields the same result. Online troubleshooting efforts have been conducted, but no effective solution has been identified. The Windows 10 system in use is a fresh installation with no prior history of IntelliJ IDEA installations. Notably, DataGrip functions correctly on this system. The application can be started via the idea64.bat script located in the bin directory; however, launching via the standard executable (.exe) is unsuccessful. System environment variables have been verified and appear to be correctly configured. The issue was reproduced on a colleague's Windows 10 machine during diagnostic testing, yielding identical results.

Hi Linhai00375 , it looks like something is misconfigured in the Windows OS side. Cause the exe requires system-level component, which is a different path with bat file.
Please direct to the bin folder of the IDEA installation directory in Command Prompt (cmd, not PowerShell), and run the following command accordingly.
1. Run “winver” and share the Windows version details with us.
2. Run “set IJ_LAUNCHER_DEBUG=true"
3. Run “idea64.exe” and share all the output with us.
For more details, please refer to https://intellij-support.jetbrains.com/hc/en-us/articles/360011901879-How-to-start-IDE-from-the-command-line.
By the way, you can also double-click the idea64.exe inside the bin folder of the IDEA installation directory and see if it works or not. Thank you.
1. OS: Windows 10 22H2 (Build 19045.6456)
2. Issue: The app just hangs—no response, no output.
3. Issue (continued): Same thing—completely unresponsive, no reaction at all.
Additional note: No reaction at all.
Hi Linhai00375 , thanks for sharing the screenshot.
Please back up and remove the following directories - backup means copying these folders to somewhere else:
%APPDATA%\JetBrains\IntelliJIdea2026.1
%LOCALAPPDATA%\JetBrains\IntelliJIdea2026.1
Then uninstall IntelliJ IDEA, and remove C:\Program Files\JetBrains\IntelliJ IDEA 2026.1.3
Then install IntelliJ IDEA again: https://www.jetbrains.com.cn/idea/download/?section=windows
Please double-click the idea64.exe inside C:\Program Files\JetBrains\IntelliJ IDEA 2026.1.3\bin after reinstallation, thank you.
