`cargo run` fails with `Access is denied. (os error 5)` on Windows 10 #11544

SamCNexor · 2023-01-05T14:06:05Z

Problem

Following the instructions on https://www.rust-lang.org/tools/install I used rustup-init.exe to install Rust on my Windows 10 machine.

I created a new Rust project by running cargo new playground in PowerShell, changed to the new directory with cd \.playground\, and ran cargo run. The error I get is as follows:

PS C:\Users\myname\playground> cargo run
    Finished dev [unoptimized + debuginfo] target(s) in 0.04s
     Running `target\debug\playground.exe`
error: could not execute process `target\debug\playground.exe` (never executed)

Caused by:
  Access is denied. (os error 5)

However, if I run the binary directly in PowerShell (after cargo build or attempting cargo run), it works:

PS C:\Users\myname\playground> .\target\debug\playground.exe
Hello, world!

I looked up several similar issues to this, but these didn't lead to any solutions:

Things I have tried so far which don't fix the problem:

Re-running the rustup-init.exe installer
Restarting my machine
Compiling the source code directly with rustc, copying the binary into target\debug\playground.exe and then running cargo run
cargo run with RUST_BACKTRACE=1 and CARGO_LOG=trace environment variables to try and diagnose the issue - no extra useful output
Checking the file/folder permissions on the binary and the target directory - permissions look fine to me
Re-doing the above steps but using Command Prompt instead of PowerShell
- This was interesting because executing the binary directly produces an Access is denied. error, whereas this approach works in PowerShell
Re-running the rustup-init.exe installer as administrator (without uninstalling as a regular user first)

One thing I have not tried yet is disabling my antivirus, because this is managed by my company. However, I have seen people with a similar issue to myself (see links above) and they mention that disabling antivirus did not fix the issue for them.

Steps

Install Rust via https://www.rust-lang.org/tools/install on a Windows 10 machine
Open PowerShell
Create a new Rust project with cargo new playground
In the new project directory run cargo run (should produce the error)
Run the binary directly with .\target\debug\playground.exe (should work successfully)
Open Command Prompt
In the project directory run cargo run (should produce the error)
Run the binary directly with .\target\debug\playground.exe` (should produce the error)

ehuss · 2023-01-05T14:27:17Z

Hm, that's quite strange! Some questions:

Can you say which anti-virus product (and version) you are using?
Which powershell are you using (type $PSVersionTable)?
What Is the execution policy (type Get-ExecutionPolicy -List)?
Are there any non-default system policies?

SamCNexor · 2023-01-05T14:56:07Z

Our anti-virus is Windows Defender Antivirus. Versions here:

Antimalware Client Version: 4.18.2211.5
Engine Version: 1.1.19900.2
Antivirus Version: 1.381.1761.0
Anti-spyware Version: 1.381.1761.0

PowerShell version:

PS C:\Users\myname\playground> $PSVersionTable

Name                           Value
----                           -----
PSVersion                      5.1.19041.2364
PSEdition                      Desktop
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0...}
BuildVersion                   10.0.19041.2364
CLRVersion                     4.0.30319.42000
WSManStackVersion              3.0
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1

Execution policy:

PS C:\Users\myname\playground> Get-ExecutionPolicy -List

        Scope ExecutionPolicy
        ----- ---------------
MachinePolicy    RemoteSigned
   UserPolicy       Undefined
      Process       Undefined
  CurrentUser       Undefined
 LocalMachine       Undefined

Yes, I think there are non-default system policies, but I don't know them in detail I'm afraid.

From your questions it sounds like this might just be my environment not allowing me access - I will talk to the policy issuers and see if they can give any more insight.

ehuss · 2023-01-05T16:32:18Z

Hm. RemoteSigned is not the default, but I tested on my local machine and it didn't seem to make a difference.

Another random thought is to check if there are any AppLocker policies. I think those can be listed with Get-AppLockerPolicy -Effective.

Another place to check is the Event Viewer and scrounge around to see if there are any events logged when the Access is Denied error is raised.

Otherwise, I'm not familiar with Windows policies or anti-virus controls, so I probably won't be able to help much more. Perhaps there are some Windows experts at one of the forums like https://users.rust-lang.org/?

SamCNexor · 2023-01-06T09:35:18Z

AppLocker policies:

PS C:\Users\myname\playground> Get-AppLockerPolicy -Effective

Version RuleCollections RuleCollectionTypes
------- --------------- -------------------
      1 {}              {}

I will investigate the Event Viewer and update this thread if I find anything interesting.

It seems right now that my problem is being caused by a policy on my machine causing the issue, not necessarily a problem with cargo itself. I'll continue investigating. Thanks for your help so far.

weihanglo · 2023-02-19T10:24:58Z

Hey. Thank you for helping the investigation. I am going to close this issue to make the way too long issue backlog less scary. If you find anything interesting or any improvement Cargo can do for this situation, feel free to comment below or open a new issue. Thank you again!

linsaftw · 2023-03-27T17:05:59Z

I have the same error. I am new to this programming language. I am using Windows 11.

SamCNexor · 2023-03-31T10:22:16Z

I found a workaround for this after some more searching: https://stackoverflow.com/a/74170163

Adding the Rust workspace folder to Microsoft Defender's exclusion list prevents the problem from happening.

I'm not sure there is anything Cargo can do in this situation, it's more related to OS security policies than the program itself, so I am happy if this thread stays closed. Thanks for everyone's help.

linsaftw · 2023-03-31T12:35:47Z

In my case it was avast hardened mode.

muratozgul · 2023-05-15T16:16:30Z

In my case, the program was already running in Visual Studio Code's terminal and I was trying cargo run in powershell

zhongdongy · 2023-09-09T04:19:22Z

Just add the project directory to Windows Security program exclusion list and it should be fine.

waki285 · 2023-09-17T13:35:48Z

in my case, it was by ESET antivirus. disabled it to solved

askor · 2023-10-06T15:48:45Z

On Windows 10 I had to click

Virus & threat protection > Virus & threat protection: Manage settings > Exclusions: Add or remove exclusions > + Add an exclusion

carsonkrueger · 2023-10-16T04:40:48Z

Just add the project directory to Windows Security program exclusion list and it should be fine.

This fixed it for me, thanks

oisyn · 2023-10-18T23:03:40Z

Windows Security was the culprit for me as well. I hooked up ProcMon to see what exactly gave the error, and it was a call to SetRenameInformationFile on file egui_node_graph\egui_node_graph_example\target\wasm32-unknown-unknown3X35gS
context:

ReplaceIfExists: True,
FileName: egui_node_graph\egui_node_graph_example\target\wasm32-unknown-unknown

Note that I was running trunk serve which in turn called cargo, don't know whether that matters.

ChrisDenton · 2023-10-18T23:30:49Z

Hm, my guess is that happens because the directory wasm32-unknown-unknown unexpectedly still exists. The documentation for Rust's std::fs::rename notes that it will fail if a directory already exists at the destination.

Edit: actually a better guess is the security software has a lock on something in the source directory. This would also prevent renaming the ancestor directories. A quick fix would be to keep retrying the operation with a back-off until either it succeeds or some arbitrary limit is reached (whichever comes first).

Traxpoint · 2024-03-18T13:15:58Z

Seems it comes with last MS or similar updates. New projects won't work like described above. Older ones are working for me. Cargo run then does it without OS error 5.

Mergpijp · 2024-07-26T18:14:45Z

I did a cargo clean and the deleted cargo.lock it seems fine now

ojob · 2024-12-09T08:59:14Z

It seemed it would work for me, but alas it failed with same OS error. After some trials, it does not always stop at the same point thought.

Last week, my company installed an upgrade of the antivirus on my development computer, and it really seems to be the root cause.

ChrisDenton · 2024-12-09T09:02:40Z

If you're able to use dev drive on your developer computer then that might improve the situation.
