@raja-rahamath Thanks for reporting this with all the specifics! I was able to reproduce this bug on Windows. I have written a fix, will release it in the night (with the conda package and updated installation instructions) and then update here.

Meanwhile, you'll need to install ghostscript from https://www.ghostscript.com/download/gsdnld.html.

After installation, you'll need to reboot your system to make sure that the ghostscript executable is in your PATH. Alternatively, if you don't want to reboot, you can manually add the path to ghostscript installation's bin folder to the windows PATH variable as shown here. https://java.com/en/download/help/path.xml

You can also check out this SO answer for instructions about adding the ghostscript executable to the windows PATH variable.

Hi thanks for the reply, I have tried the suggested solution by installing ghostscript and adding it system environment and rebooting, still I am getting the same error, kindly advise

@raja-rahamath, I've added a fix for this in the master branch, will create a release today that you can install later using pip.

However, if you want that fix ASAP (and help me test the fix!), you can install Camelot with the steps described here.

[vinayak-mehta]

@raja-rahamath You can now install 0.2.1 by pip install camelot-py==0.2.1, which should fix this.

Thank you very much for the support working perfectly
