Server Error when printing cheque from Journal Entry screen

I am new to ERPNext… When printing cheque from the Journal Entry screen… Server error is prompting as follows:

IOError: No wkhtmltopdf executable found: “”
If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - Installing wkhtmltopdf · JazzCore/python-pdfkit Wiki · GitHub

Can someone please advise on above error?

Seems like a damaged installation, have you tried to run/re-run a bench update?

@trentmu I believe the company who is hosting the application will have to install wkhtmltopdf. We will inform them accordingly.
You have also mentioned about run/re-run a bench update? Can you please clarify if as a user I can perform this procedure or is it still the company hosting the application who shall do that?

Thanks in Advance.

If they have to do the install, then it is most likely that you don’t/won’t be able to run the update without their help, but I would guess that you should have access to both install & update functionality on your system (it’s yours!).
Maybe host at ERPNext?
