Windows installer fails due to debug runtime dependency (vcruntime140d.dll and ucrtbased.dll)

[Christina Krieg]

Hi HTCondor team,

I wanted to report a bug in the HTCondor Windows installer that prevents installation on machines without Visual Studio.

Problem: The installer fails during the MakeAdminToken custom action with error code 1722 / 0xC0000135 (STATUS_DLL_NOT_FOUND).
Running win_install_helper.exe manually reveals the root cause:

vcruntime140d.dll and ucrtbased.dll are missing

Both dlls are debug versions of the Visual C++ runtime. It is not included in the standard Visual C++ Redistributable and is only available on machines with Visual Studio installed.
A release build should link against vcruntime140.dll and ucrtbase.dll instead.

Impact: Any Windows machine without Visual Studio installed will fail to install HTCondor.
Installing the Visual C++ Redistributable does not resolve the issue because it only ships the release runtime.

Workaround: Copying vcruntime140d.dll and ucrtbased.dll from a machine with Visual Studio allows the HTCondor installation to proceed.

Steps to reproduce:

1.) Download the HTCondor Windows MSI installer
2.) Attempt to install on a machine without Visual Studio
3.) Installation fails with error 1722 during MakeAdminToken
4.) Run C:\condor\bin\win_install_helper.exe manually — Windows reports vcruntime140d.dll and ucrtbased.dll are missing

Fix: Recompile win_install_helper.exe in Release mode so it links against vcruntime140.dll and ucrtbase.dll.

Please let me know if you need any additional information such as the full installer log.

Best regards,

[Christina Krieg]

Sorry, I forgot to mention the HTCondor version. Its 2025.x

Hello Christina,

The issue installing HTCondor on Windows is resolved with the HTCondor 25.12.2 release.
