This issue can be fixed by installing the following Microsoft mediafeaturepack (x64 version): KB4039813
Can be downloaded from here:
https://www.microsoft.com/en-us/software-download/mediafeaturepack

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.

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

13

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

14

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

15

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?
