VCRUNTIME140.dll crash when connecting (file is present)

[ncflagg]

When I attempt to connect via WiFi or USB, the Windows app crashes. What VCRUNTIME140.dll version are you using that is working? What's its file size?:

Faulting module name: VCRUNTIME140.dll, version: 14.44.35211.0, time stamp: 0x0f259d81
Exception code: 0xc0000005

• Phone Model: Pixel 3
• Android Version: 12
• Connection Method: Both WiFi and USB seem to fail the same way
• Windows 10 22h2

Troubleshooting:

• Tried VCamdroid versions 1.3 and 1.3.1
• I've tried the 64-bit versions 14.44.35211.0 and 14.50.35719.0 of the VB runtimes
• I've also looked for other versions of the VCRUNTIME140.dll on my drive and tried randomly copying 5-6 of them directly into the VCamdroid installation directory
• I have registered the DLL as administrator
• Tried running the Windows app as admin
• I have Windows firewall completely disabled and no antivirus installed
• Ping works in both directions
• I ran Angry IP scanner against the phone (while the camera app was open) on ports 6969, 8554 and 39029 (my randomly-assigned debug port) and only the debug port shows open
• I can see the ADB device and am able to install the APK

* daemon started successfully

Android Logs:

• There is no bug icon (or any other icon) I can see in the Android app to attempt to view any logs

vcamdroid.log, trying via USB:

Install the latest supported version of the VC runtime (the one that has support up to Visual Studio 2026).

Also I don't think copying the .dlls in the app folder works, you need to use the installer

That's what I had done just before gathering the Windows Application logs. I had updated them and originally had version 14.50.35719.0. Later, I saw a hard link in the ReadMe for this repo (https://aka.ms/vs/17/release/vc_redist.x64.exe), and (uninstalled the prev version first) installed that version. I ended up with an older version in 14.44.35211.0. So, it seems that I had the latest version from the get-go

That's why I asked what version is working for you?

Also I don't think copying the .dlls in the app folder works, you need to use the installer

Fair enough. Maybe it won't work in this instance, but it's a tried-and-true method I've used to fix many other apps in the past. Maybe there's some other cause here that just looks like an incompatibility.

On my PC i have multiple vc++ redistributable versions: 14.50.35719, 12.0.40664 and 11.0.61030.

I tested the app on Windows Sandbox, so I don't have any .dlls installed, so no vcruntime. I got the same error on the first launch, but after installing the latest redistributable from https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-supported-redistributable-version it worked normally, the app started and got no errors.
