@Elias:

Hi, I'm using Windows 7 and I want to play a video game but a message appears that says "The program can't start because VCRUNTIME140.dll is missing from your computer. Try reinstalling the program to fix this problem", and i am 13 years old and I don't know how to solve this problem

Download and install both the x86 and x64 versions of the Visual C++ redistributable package:

• x86: vc_redist.x86.exe
• x64: vc_redist.x64.exe

There is no such thing as "Straight C++". There will always be some library functions that you are calling here and there in your code, and even if you are very careful not to, there will be some functions that will need to be called simply by code emitted by the compiler. For example if you have the following loop:

for( int i = 0;  i < count;  i++ )
    array1[i] = array2[i];

The compiler will replace it with code which simply copies the memory over. And if you are compiling for smaller size instead of speed, this will be a call to a function very much like memmove().

Also, you may have some floating point operations for which there exist no direct x86 equivalent instructions; these will also be implemented with function calls. And the list goes on.

This does not make your code platform dependant, because on a different platform the compiler of that plafrom will compile the same code of yours to go with whatever is the C++ runtime for that platform.

Luckily, the C++ runtime does not have to be a separate entity from your application. Check your compiler and linker options; you should be able to produce a single executable which contains both. If you have found that g++ does not require a separate runtime, it is because it does exactly that by default.

Exactly the info I needed.

Thanks for all your help. Be well!

Hi ,

Open, as an administrator, the Windows Registry by typing "Regedit" into the Windows Start button.

Go to HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products.

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products to remove MSI

Go to "Edit" and look for the missing *.msi file that was called out in the error message.

Reinstall using Visual C++ AIO after download extract the install.bat file right click run as administrator.

Hello John,

I'm Tiaen and I'm an independent advisor in this community and here to help you.

I'm sorry for having this issue.

0x80070641 means ERROR_INSTALL_SERVICE_FAILURE - The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed.

You may try the follow steps to check if these methods fixes the issue:

#Method 1: Check Windows Installer service.

Go to Start > Run > type in services.msc > OK.

The Services window will open, scroll down to Windows Installer and double click on it.

The Properties window will open, on the drop-down menu (Start up type) select 'automatic' > OK and close windows.

Reboot PC and test.

If issue persist, proceed to next method.

Method 2: Unregister and re-register the Windows Installer

Click Start, click Run, type MSIEXEC /UNREGISTER, and then click OK. Even if you do this correctly, it may look like nothing occurs.

Click Start, click Run, type MSIEXEC /REGSERVER, and then click OK. Even if you do this correctly, it may look like nothing occurs, or you may briefly see an hourglass. After you run this command, the operation is complete.

Try your Windows Installer-based application again.

Please share with me the results.

Best regards
