This issue can be fixed by installing the following Microsoft mediafeaturepack (x64 version): KB4039813
Can be downloaded from here:

In the meantime we are working to update the product documentation as well. We have yet to issue a 2018.1 official doc.

also, please confirm that it worked, after installing.

Hey, I am using windows 7, the feature pack shows for windows 10. Will this work for windows 7 too?

Its not installing for windows 7. any other fix which i can use for win 7

try this one here:

Hey, This Update isn’t installing and giving a message “This update is not applicable to your computer”. Can you advise any other way?

can you tell me exactly what version of windows you have? print screen if possible, like this:

(update KB2533623) try this one also


This is happening after CE automatically updated to 2018, none of the image related workflows are working.

yes, becasue we ve upgraded the detection engine and you need a windows kb as prerequisite.
try the last suggestion i ve sent

tried KB2533623 before posting here, didn’t work . Maybe a fresh installation of 2018 would work ? but i am unable to receive the installer on my email when i request for one

Its not a problem with the install, there are some Windows dlls that are mising and we need them. I will have to do more research for your exact win7 version, for the proper KB.
Can you use google OCR - screen scraping? Can you try it?

On using google OCR, i am getting the following error " The program can’t start because api-ms-win-crt-runtime-l1-1-0.dll is missing from your computer"


Ok thank you, we will investigate and get back to you asap, we just need to find the kb that its missing

Try this one, please. Don t forget to confirm if it fixes the problem so we can share to others if they face the same issue.


This worked after installing the update, Thanks a lot!

Thank you too
