I get the following error output while running in windows 32 bit

I am facing exactly the same issue.

Here is the error. Kindly suggest the resolution as early as possible:)

Did any one find any solution for this problem?

Try downgrading Tesseract from version 4.00.00alpha to version 3.05.01. The version check built into the pypdfocr package is expecting the version numbers to be integers, hence the error on '00alpha' (note: the version checker does account for 'dev' versions, just not versions ending with strings other than 'dev').

[swoldetsadick]

ver = [int(x) for x in ver_str.split('.') if x.isdigit()]
req = [int(x) for x in self.required.split('.') if x.isdigit()]
This is how it should be...
