Api-ms-win-crt-heap-l1-1-0.dll is missing

I get this error on my Windows 10. It says, " The program can’t start because api-ms-win-crt-heap-l1-1-0.dll is missing. Try reinstalling to fix the problem." I reinstalled but the issue still persists. Any help on this topic, please?

Have a look at the screenshot:

go and get Visual Studio runtime libraries and install them:


Just copy all of these files from where Xojo Is Installed on your dev computer --> /Extras/Windows Runtime/Files

Select either the 64/32 bit versions.


Thanks to both of you for your valuable suggestion. I solved it another way. I actually downloaded the missing DLL file from this trusted site: [link removed], which was a suggestion of my friend. It actually fixed my problem. Anyway, THANKS ONCE AGAIN.

Don’t use dll from such a download page. You never know wether it is manipulated!


Yeah… I’m not sure how “dlldownloads” is more trusted than Microsoft…
