Looks like I have issues with filenames that are just numbers. I'll have to change some internal temporary file naming to fix this. In the meantime, if you add some letters to your filename, it should work fine.

Fixed in 0.6.1

I see the same issue in the latest version. Any idea?

[kaumaron]

@farrukhdGB , I know you asked about a year ago but for posterity:
I had to downgrade from tesseract-4.00.00 to tesseract-3.05.02 to get it to work.
According to one of the posts on Bounty Source it's throwing that error on the tesseract version name.

Edit: it's a reference to Issue #61.
