How do I fix lnk1168 error?

• Remove From My Forums

• Question

• When I first compile and link a solution, everything works fine. However, often (about 60 - 70% of the time), subsequent link operations fail unable to open the .exe file for writing. I've checked the obvious things such as the application still running and even trying to delete the existing file via explorer fails saying the file is in use.

  If I wait long enough - sometimes up to 5 minutes - then all works well again. I haven't worked out when this happens. It usually happens if I encounter an unhandled exception during a test run, but sometimes I get this even when the test run was clean.

  Any ideas?

Suddenly, my Visual Studio Express 2010 C++ stopped rebuilding my project. When I first hit F7 the project builds and runs fine (heck, it's a hello world example).

Then I make some changes and hit F7 again, then I get:

1>LINK : fatal error LNK1168: cannot open C:\Users\username\Documents\Visual Studio 2010\Projects\console\Debug\console.exe for writing**<br><br>

Now the funny thing comes:

1. The app is not running and it's not shown in the Task Manager.
2. Going into the project directory and trying to remove it with hands comes with success but the file APPEARS AGAIN FROM NOWHERE.
3. The system restore is disabled.
4. I also tried to take the ownership of the whole damn drive.
5. Every time I delete the file it recreates itself again but sometimes it stops doing that.
6. If I delete the file (and it recreates after that), and then I start sysinternals procmon then the file disappears.
7. If I start procmon before - then the file keeps appearing after delete like always.

OS: W7 SP1 64-bit, with latest updates

Any ideas, please?

The problem is probably that you forgot to close the program and that you instead have the program running in the background.

Find the console window where the exe file program is running, and close it by clicking the X in the upper right corner. Then try to recompile the program. In my case this solved the problem.

I know this posting is old, but I am answering for the other people like me who find this through the search engines.

I've encountered this problem when the build is abruptly closed before it is loaded. No process would show up in the Task Manager, but if you navigate to the executable generated in the project folder and try to delete it, Windows claims that the application is in use. (If not, just delete the file and rebuild, which generates a new executable) In Windows(Visual Studio 2019), the file is located in this directory by default:

%USERPROFILE%\source\repos\ProjectFolderName\Debug

To end the allegedly running process, open the command prompt and type in the following command:

taskkill /F /IM ApplicationName.exe

This forces any running instance to be terminated. Rebuild and execute!

Restarting Visual Studio solved the problem for me.

In my case, cleaning and rebuilding the project resolved the problem.

If the above solutions didn't work, you can try this which worked for me.

Open an elevated command prompt (cmd -> Run as administrator), then write following command and hit enter:

wmic process where name='YOUR_PROCESS_NAME.exe' delete

If you see a message: Instance deletion successful., then you will be again able to build and run project from VS.

e.g. in OP's case, the command will be:

wmic process where name='console.exe' delete

well, I actually just saved and closed the project and restarted VS Express 2013 in windows 8 and that sorted my problem.

The Reason is that your previous build is still running in the background. I solve this problem by following these steps:

• Open Task Manager
• Goto Details Tab
• Find Your Application
• End Task it by right clicking on it
• Done!

This solved same problem I also came across very well

1. Close the app if it is still running on the taskbar,
2. Open cmd (command prompt) and run the following

taskkill /F /IM ApplicationName.exe

1. Rebuild your project!! error solved!

This can also be a problem from the improper use of functions like FindNextFile when a FindClose is never executed. The process of the built file is terminated, and the build itself can be deleted, but LNK1168 will prevent a rebuild because of the open handle. This can create a handle leak in Explorer which can be addressed by terminating and restarting Explorer, but in many cases an immediate reboot is necessary.

I know this is an old question but thought I'd share how I resolved the issue.

If you're using Visual Studio and this error occurs, you can try to attach to process (CTRL+ALT+P) and find the "(program).exe" process. When you try to attach to it, an error will display stating that it failed to attach which removes the process from "running" (even though it's not...) You'll also be able to delete the (program).exe from your Debug folder.

Hope this helps someone! :)

FINALLY THE BEST WAY WORKED PERFECTLY FOR ME

None of the solutions in this page worked for me EXCEPT THE FOLLOWING

Below the comment sections of the second answer, try the following :

Adding to my above comment, Task Manager does not display the filename.exe process but Resource Monitor does, so I'm able to kill it from there which solves the issue without having to reboot. – A__ Jun 19 '19 at 21:23

If none of the above suggested work for you, which was the case for me, just change the project name. It creates a new exe in the new project name. Later when you restart, you can change it back to your original project name.

I know this is an old thread but I was stumbling in the same problem also. Finding it in task manager is tricky, and I started to grow tired of having to restart my PC every time this happened.

A solution would be to download Process Explorer and there you can search for running tasks. In my case I was having the following error:

1>LINK : fatal error LNK1168: cannot open C:Out\Build\VS12_app\Debug\platform_test.exe for writing [C:Build\VS12_app\platform_test.vcxproj]

I searched for C:Out\Build\VS12_app\Debug\platform_test.exe in Process Explorer, killed it and I was able to compile.

I also had this same issue. My console window was no longer open, but I was able to see my application running by going to processes within task manager. The process name was the name of my application. Once I ended the process I was able to build and compile my code with no issues.

Start your program as an administrator. The program can't rewrite your files cause your files are in a protected location on your hard drive.
