PAD failed to extract text with OCR

(0) ShareShare
ReportReport
Posted on by schill27 17

I am currently running PAD version 2.36.140.23262 with Windows 10. Since upgrading to this version, my flows that use OCR are now failing.

 

To test this, I created a simple, one action flow:

schill27_0-1696355248758.png

Running the flow produces two different error messages, depending on file type.

 

For .JPG I get:

Is this an issue with the current version of PAD or has OCR changed?

    If it worked in a previous version, but does not work after an update, it likely is a bug. I suggest reporting this as a bug to MS support and having them fix it. In the meantime, if you actually need the functionality, I suggest rolling back to a previous working version. If you do not have an installer for that, you can ask MS support to provide it to you.

    Out of Memory error after Power Automate Desktop update

    I recently updated Power Automate Desktop to the latest version, and since then I have been experiencing Out of Memory errors when trying to run certain flows. I have tried restarting my computer and Power Automate Desktop, but the errors persist.

    I have also tried installing older versions of Power Automate Desktop, but I cannot find the installers for these versions in the documentation. Does anyone know where I can download older versions of Power Automate Desktop, or how to contact Microsoft Support about this issue?

    I was able to find some older versions here: Install Power Automate - Power Automate | Microsoft Learn. Versions 2.32 and earlier downloads can be found in the yellow warning panel. Note, 2.33 actually links to the newest version, so avoid that.

    Thanks, it works for me with 2.32 version but when I tried to open the flow with the 2.32 version it tells me that:

    "This flow has been generated by a newer Power Automate version than the one currently installed. Download and install the latest version of Power Automate and try again".
    Does anyone knows which version is the more stable with this OCR Action?

  • Agnius Bartninkas Profile Picture

    Well, if you have edited your flow with the latest version, it will likely not work with any previous version anyway. But I would suggest trying to revert to the one you had previous to the update. If you do not know which version you were on, you can try looking for the installation logs in the Application logs under the Windows Event Viewer.

     

    Again, this seems like a bug and you'd be best to contact MS support about it. They can then fix it, and also possibly provide an installer for a previous version. Most installers for previous versions are not publicly available.

    If your issue got resolved by reverting to a previous version, can I suggest marking my reply as an accepted solution?
