OCR : Microsoft OCR/Cloud OCR/ Abby OCR giving same error : "InvalidImageInput"



Is this happening with Microsoft OCR or Microsoft Cloud OCR?


this is happening with Microsoft OCR

and Abbyy OCR didn’t work too,
only default engine [Google OCR] works.

with Abbyy OCR ,there is an error like this.
Main has thrown an exception

I reinstalled SharePoint designer and now Microsoft OCR is work fine.:grin:


I am using UiPath Studio Community version 2016.2.6253 Beta on a Windows 7.
Tried with beta and without beta and I can only get it working with Google OCR, Microsoft OCR always throws that Exception. It looks like it needs a dll or something like that but even in the logs no info is given in that way.


I have still same problem. Only Google OCR is working. I have version 2016.2.6274.
So is there way to fix it or go around the problem?


make sure you have the SharepointDesigner2007 properly installed



If we do not install SharePoint Designer, can we still use “Microsoft OCR” function? thanks~


It comes preinstalled with Windows 10. Otherwise you can install it from here Uipath - Install MS Office OCR.


Hi Guys,
I am able to OCR the content from Abbyy Cloud OCR Engine.

Step 1.
Register your self on https://cloud.ocrsdk.com

Step 2.
Post Registration you will receive Application Id and Password.

Step 3.
Please drag Get OCR Text and Abbyy Cloud COR Engine from Activities Panel and enter App Id and password received from Abbyy Team post registration and everything will start working.

Please let me know if you need further help.

Missing Microsoft OCR in Screen Scraping Wizard
How to Integrate OCR engine to UiPath?

I have “Abbyy OCR : Error performing OCR: AbbyyErrorLoadEngine”.
Does anyone have the same issue? All other OCR engines are working.
Maybe I need to install something before?


yes, abbyy engine, with a license :slight_smile:


Hi all, as the issue mentioned above, though i have installed the SharepointDesigner and the version of my UiPath is 2008.1.2 Enterprise, i still couldn’t use Miscrosoft OCR. It always show the error MicrosoftErrorCreate Engine. Anyone knows how to solve the problem?


Same error… I re downloaded SharePoint Designer 2007


When you install the sharepoint designer kit, do you select the MODI feature? By default thats disabled


Hi Gabriel,
i installed Microsoft Sharepoint Designer 2007, still my Microsoft OCR is giving --> Error performing OCR:MicrosoftCreateEngine Exception can you help me with this.


The only issue here is a incomplete sharepoint designer install
