Application cannot run due to missing dll files

[safval]

Overview

If the application is installed on a freshly reinstalled Windows system, it cannot launch. The system shows the error message:

KeePassXC.exe - System Error.
The code execution cannot proceed because VCRUNTIME140.dll was not found. Reinstalling the program may fix this problem.

The same message is repeated for VCRUNTIME140.dll, VCRUNTIME140_1.dll, and VCRUNTIME140.dll.
Installing on Windows Sandbox gives the same result.

Steps to Reproduce

1. Enable the Windows Sandox and open it.
2. Copy KeePass installator (KeePassXC-2.7.6-Win64.msi) into the sandbox window.
3. Install KeePass.

Expected Behavior

KeePass starts.

Actual Behavior

Error messages are shown.

Context

KeePassXC - 2.7.6

Operating System: Windows 11 Pro 22H2 OS build 22621.2134

Duplicate of #7564. You need to install the MSVC Runtime library.

Installers have that duty, don't they?

MSI installers cannot piggyback third-party dependencies. Thank Microsoft for this.

There is a tool in Qt5 called windeployqt.exe. It intends to gather all necessary files. It's possible that its --compiler-runtime flag can help to fix this problem.

No, that's not how that works, but thank you

We could ship the DLLs as part of KeePassXC, but since Windows cannot keep those up to date, it is explicitly discouraged by the MSVC docs.

Okay, I understand now. I didn't assume it was done on purpose.
