Hello，

Thanks for your reply.
Please be informed that our Spire.OCR only supports running on projects with x64 platform. Additionally, you need to add several additional dll files to your project, which Spire.OCR depends on. Please follow the steps in thistutorial to test. If there are still problems, please feel free to back at any time.

Althoug First I installed

From
https://www.nuget.org/packages/Spire.PDF/10.9.0
https://www.nuget.org/packages/Spire.OCR/1.9.8

Then as per your reply

https://www.e-iceblue.com/Tutorials/NET/Spire.OCR-for-.NET/Program-Guide/Recognize-Text/How-to-use-Spire.OCR-in-.NET-Framework-Applications.html

from above link I copied the respective DLLs
Again I get same error Pl see the image below and scroll to see the OUTPUT message

Screenshot (7).png

I usually open in Windows Forms.App(.NET Framework)
and per your above link it mentions to open in Console App(.NET Framework)



For VS 2019
Tried your following steps

Step 2: Change the platform target of the application to X64.

In the application's solution explorer, right-click on the solution name and then click "Properties".

Your Link Image Is quite different from What is there as per below image

Do I re-do everything UnInstall again Install with proper steps
