Hi,

 Found FMA
 Found SSE
 Found libarchive 3.3.2 zlib/1.2.11 liblzma/5.2.3 bz2lib/1.0.6 liblz4/1.7.5

I am trying to extract the text from attached image. But it does not work 
and returns following error

Warning: Invalid resolution 0 dpi. Using 70 instead.
Estimating resolution as 450
Empty page!!
Estimating resolution as 450

Also it generated attached tiff file when I ran tesseract command as 
(tesseract captcha5.png stdout -c tessedit_write_images=true)

Can someone please advise how we can extract the text here?.

Regards,
Durai.
