CRHM_GUI.exe does not open on Windows 11 (64-bit) – silent crash on startup

[ClarGl]

Description:

I installed CRHM v1.3.5 on Windows 11 (64-bit) using the official release from this repository. When launching CRHM_GUI.exe, the cursor shows a loading indicator (hourglass) for about one second and then nothing happens. No window appears, no error message is shown.

What I have tried:

• Installed all Visual C++ Redistributables (2013, 2015–2022, x64 and x86)

• Ran the executable as Administrator

• Set compatibility mode to Windows 8 and Windows 7

• Verified all DLL dependencies using the Dependencies tool – no missing (red) entries found

• Confirmed that 'platforms\qwindows.dll' is present in the installation directory

• Moved the entire installation to 'C:\Users<user>\CRHM' to rule out write permission issues in 'C:\Program Files'

• Launching from PowerShell produces no output whatsoever (.\CRHM_GUI.exe 2>&1 returns nothing)

Environment:

• OS: Windows 11, 64-bit

• CRHM version: v1.3.5

• Installation path tested: 'C:\Program Files\CRHMcode\CRHM_GUI' and 'C:\Users<user>\CRHM'

Is this a known issue with Windows 11? Any hints on missing dependencies or required configuration would be greatly appreciated.

Have you install an evaluation version of TeeChart program? TeeChart program is required to use CRHM_GUI applicaiton.

You can find out more information for installing CRHM_GUI from Page 31 to 35 on CRHMdoc-1.3.5r.pdf

Let me know if this resolves the issue.

Thank you for the TeeChart hint! CRHM_GUI.exe now launches successfully and main window appears.

However, silent crash at Build > Construct:

• Click "Build > Construct" → Hourglass for 1 second → Program closes completely without error message
• Event Viewer: No Error/Critical entries (only MsiInstaller Info logs)
• PowerShell: No output (.\CRHM_GUI.exe 2>&1 returns nothing)
• Tested with Win7/8 compatibility mode + Administrator rights

Is the Construct crash known on Windows 11?

For the crash at Build > Construct, it is shown on Windows 11. It is tested and runs fine on Windows 11.

I am wondering a few things you did on your Windows 11 might cause this. See the following things from your first post:

**Installed all Visual C++ Redistributables (2013, 2015–2022, x64 and x86)

Ran the executable as Administrator

Set compatibility mode to Windows 8 and Windows 7

Verified all DLL dependencies using the Dependencies tool – no missing (red) entries found

Confirmed that 'platforms\qwindows.dll' is present in the installation directory**

None of these above are needed to run CRHM_GUI.exe once you install it on your Windows 11. Can you try again without the highlighted things from above?

I think you have already copied "CRHM_GUI" folder from C:\Program Files (x86)\CRHMcode and pasted it to a local folder, since you were able to open CRHM_GUI.exe.

Thank you for the suggestion. I uninstalled CRHM completely, deleted any remaining folders, and did a fresh install without Visual C++ redistributables, admin mode, compatibility settings, or manual folder copies. The crash at Build > Construct still occurs.

I'll test on another laptop running Windows 10 to check if it's OS-specific.

I have installed and ran CRHM_GUI on Windows 10 and 11, and I have not got crash at Build > Construct.
