Hi,

did you already follow the instructions at https://steamhost.cn/steamcommunity_com/app/4920/discussions/1/341537388320382330/ ? The game may not start if your system is missing the VC 2013 Redistributable Packages.

If that doesn't resolve your issue please run the techsupport.exe and post a link to your tech_support.zip here.

After update my game does not launch at all, I tried reinstall, file verification, tried to remove files/folders suggested above, help :( I click launch and nothing happens.

same problem

Hi,

please try to directly start ns2 via the game's exe (right-click at Natural Selection 2 in the Library -> Properties -> Local Files -> Browse Local files- > open the x64 folder -> double-click at ns2.exe) and see if that yields any error message.

Additionally we need details about the systems of affected users. So please see if you can run the TechSupport.exe . Otherwise please run dxdiag (https://support.microsoft.com/en-us/help/4028644/windows-open-and-run-dxdiagexe), save the details and post the dxdiag.txt.

Hi Ghoul, I tried via NS2.exe and received system error that says that I can`t start software due to missing D3DCOMPILER_47.dll

Hi,

I would like to add that i have 2 friends who cannot start the game.
Launching through steam makes nothing happen, launching it through the game exe file gives the D3DCOMPILER_47.dll missing issue, after downloading the dll and placing it in the folder it gives a new error with bunch of 00x00000 something. I forgot what it was exactly when i was troubleshooting it, basically, googling made it come up as a C++ runtime related error.

Neither of the computers can run the Tech_Support.exe either, which promptly crashes with the same error (either D3DCOMPILER_47.dll or c++ error) and produces no zip file.

I have tried all of the solution you have listed on the forums here and on NS2 official forums (reinstalling C++2017 and 2013, DX reinstall along with the june 2010 catalogs in steamworks, trying the DX9 folder rename in windows32 you name it I did it)
Both computers are running Windows 7; my own, which runs the game fine, is on Windows 10.

Im guessing they both arent running up-to-date Windows 7 which is why the update to C++ 2017 framework is giving them problems?

Any workaround suggestion would be appreciated.

Thanks for the comprehensive answer. So far I found two possible solutions for windows 7 users:

1. Install Windows Update KB4019990: https://www.catalog.update.microsoft.com/Search.aspx?q=KB4019990 . For more details see https://support.microsoft.com/en-us/help/4019990/update-for-the-d3dcompiler-47-dll-component-on-windows
   
2. Download the missing dll and place it in ns2's x64 folder:
   
   • Download the dll from https://drive.google.com/file/d/19frCVtnW6hP1Bnzm1wxrUVHaAJ9DxMAK/view?usp=sharing (from win 8.1 SDK)
     
   • Open your ns2 install folder: Right-click at Natural Selection 2 in your steam library -> Properties -> Local Files -> Browse Local Files
     
   • Open the x64 folder
     
   • Copy the downloaded file into the now open folder

I hope one of those solutions resolves the issue. If not please let me know.

resolved the issue for me thank you <3

Thank you for the .dll upload, that fixed it!

yep, option 2. worked for me as well, thanks Ghoul!
