You will need PCC for Sweden. The procedure is straightforward, but sending payments is a huge PITA. I still haven't figured it out, mostly because I don't want to pay $100 in transfer fees.
The only way to use that form is to install the compatible adobe reader. The file is encrypted and won't open on unsupported browsers/adobe versions. It won't help any even if I sent you the form.
I Installed the version of Adobe reader DC which was recommended in the site and used chrome browser, please let me know your configuration and browser.
When you email them the pdf, they will send you a quote with details of how to transfer the fee. I remember there was a field in the form that you will ask for the quote to be sent via email, which is faster. After transferring the money they will send the certificate. You can pay more to receive it via fast post. It is quick.
