api-ms-win-crt-runtime-l1-1-0.dll is missing - AutoCAD 2017

[TravisNave]

Problem:  After successful installation of AutoCAD 2017 on my Windows 8.1 x64 system, I received this error on launch:

The program can't start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer.  Try reinstalling the program to fix this problem.

This error did not appear on any of my Windows 7 x64 machines thus far.  I have not tested this on Windows 10 yet. 

Reason:  From what I can tell, this is caused by the usage of the new Universal CRT | Visual C++ Redistributable that is part of Windows 10.  The good news is that it seems that the installation failures for not having C++ Redistributable installed might be resolved.  The bad news is, if the prerequisite does still fail and the program does install, it will not launch.

Possible Solution:  Here are some steps to take to try and resolve this issue:

Method 1:  This is the easy method.  Follow these steps if you receive the above error.  If it still fails, go to Method 2.

1.  Go to Windows Update and make sure that your computer is fully updated.  The Universal CRT should be delivered by this method.

2.  If not, manually download and install the Microsoft Visual C++ Redistributable for your version of Windows (likely x64)

For Windows x64:
http://download.microsoft.com/download/9/3/F/93FCF1E7-E6A4-478B-96E7-D4B285925B00/vc_redist.x64.exe

For Windows x86:

http://download.microsoft.com/download/9/3/F/93FCF1E7-E6A4-478B-96E7-D4B285925B00/vc_redist.x86.exe

3.  You might have to choose uninstall first before you can install the above downloads because of previous failed installs.

4.  Reboot then try to launch AutoCAD 2017 again.

Method 2:  If the above did not work, then here is my advanced solution.  The Universal CRT files are part of the Windows 10 SDK kit.  Installing this kit and placing the CRT DLL files into the AutoCAD 2017 folder seems to resolve the issue.

1.  Download and install the Windows 10 SDK kit:

https://dev.windows.com/en-us/downloads/windows-10-sdk

2.  Copy the entire set of DLLs from the resulting location:

C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x64

3.  Paste the files into the location where AutoCAD 2017 is installed:

C:\Program Files\Autodesk\AutoCAD 2017

4.  Launch AutoCAD 2017 to complete the installation and licensing of the product. 

Conclusion:  This is a very early and crude fix for this odd issue and I am only providing it as a work-around until I can find a more stable solution to post on the board.  I do not expect this to be an issue on Windows 10.

If anyone has anything else to add, please feel free to share.

Good Luck!

Welcome to the community...

So may I ask...  Did you even try any of the information (or troubleshooting steps) that @TravisNave has stated in his article about this issue or did you just reply indicating you have this issue?

How's is this the same error?   You have a totally different issue.. 

Anyhow to resolve your issue, download and install per:

1. Access the Autodesk Virtual Agent and follow the download links to your product.
2. Download all of the parts (some applications only have a single part to download) for your product first. Do not continue until all of the parts have fully downloaded.
3. Navigate to your download folder location and extract (double click) part _001_00X.sfx.exe (or the single file download).
4. In a few seconds the extraction will start and prompt you to extract to C:\Autodesk.
5. Once the extraction is finished, the installation will automatically start.
6. Follow the installation steps for your product

If you want the full recommended installation steps, click on the installation link in my signature.

However if the installation does fail using this method, please post your installation log file here so we can review it.  Posting info: Sometimes installation log files contain personal information such as your serial #.  Prior to posting your log file please make sure to remove such info.

Good luck on your installation and report back on your progress.

I just downloaded the trial version of LT 2017, and ran into the error reported here. I've been trying to use the fixes suggested, and turned to method 2 as suggested by Travis when method 1 didn't work. Seems the Windows 10 SBK doesn't create a folder in the Program folder now, nor are there any DLL files that I could find. Looks as if the package has been modified.

Is there any other fix? The dialogue which appears when I try to launch LT suggests reinstalling the program. If I ran the installer again, would it try and plug any gaps? Alternatively, can I access older versions, or - if I bought a Windows 10 laptop, would I be able to download the software to a new machine using this account?

Thanks.

Thought I should update my own status. After playing with the installer, with no improvement, I checked the MS website. A comment on there suggested, if the software requiring the extension, is on a standalone machine, downloading all outstanding optional Windows updates for v8.1.

I had 110 updates totalling almost half a gig, but an hour later, after restart, lo and behold! LT runs! I have no idea what was in all those updates, but something installed that fixes this problem.

Sorry I can't be more specific, but if you're not on a network, and you have some updates sitting around, download them and something good might happen.

Welcome to the community.

Unfortunately you are in the wrong forum.  This forum is for users having issues when installing or licensing of their Autodesk product.  You are asking specific questions or how to workflows for a given application.  Please re-post in the proper forum.

Update:  Also (and this is very important)..  Please do not hijack another posting that has nothing to do with AutoCAD Adv Steel and change the subject matter.  May I ask why you even did this or even pick this posting to hijack?

If you experience this error during the start of the program

ou need to (re)install the Visual C++ Redistributable for Visual Studio 2015, either via Windows Update or download and directly install the Visual C++ Redistributable
