64-bit SumatraPDF NPAPI plugin

[ehrbar]

I use 64-bit Pale Moon.
I use 64-bit SumatraPDF as my primary PDF reader.
With the disabling of the internal Pale Moon PDF reader as of version 27.0, I need a plugin to view PDFs.
I cannot find any source to download the 64-bit version of the SumatraPDF NPAPI plugin. In particular, the version that was linked by Moonchild on these forums at ftp://archive:get@ftp.palemoon.org/misc ... .2-x64.zip is now apparently inaccessible.

So, can anybody point me to a source for that file?

You need to download and install an older revision of SumatraPDF first (perhaps from the 2x series), and install the PDF plugin. Then upgrade to the current version and "keep" the plugin installed.

Sorry, you don't seem to have understood at all.

The available-for-download official 2.x series SumatraPDFs are 32-bit builds, and the plugin from them does not work with 64-bit Pale Moon and 64-bit SumatraPDF. It would do absolutely no good for me to install any of the official 2.x series downloads.

The old unofficial-alternative 64-bit builds of the 2.x series were taken down back by their compilers a while ago, and any references you find online are dead links. Therefore, it is impossible to download and install one of them.

The 2.5.2 NPAPI plugin compiled for x64 used to be available from the Pale Moon FTP site at ftp://archive:get@ftp.palemoon.org/misc ... .2-x64.zip but no longer is.

Therefore, I need someone who actually and personally has the proper x64-compiled 2.5.2 plugin (or whole package) to send it to me, or for someone who has actually and personally verified by testing a link to the proper x64-compiled 2.5.2 plugin (or whole package) to provide that tested-just-before-posting link.

It's still there, it's just the link was out-of-date.
Here is the current link: ftp://archive:get@ftp2.palemoon.org/misc/Sumatra-PDF-2.5.2-x64.zip

For anyone interested, here's where the link to that file was originally posted: PDF document reading in PMx64

Wooo! Thank you thankyou thankyouthankyou!

No I understood. However, I used an experimental x64 build from another author who recompiled the app for 64-bit use, and I have only recently migrated to the x64 version provided by the original author. Funny, for awhile he saw no need to even provide an x64 app.

I built a new version using the plugin source code merged with the latest code of sumatrapdf. The extension uses sumatra pdf directly so this is not really necessary though. The source code is here. It compiles well with VS2015: https://github.com/helohe/sumatrapdf

Where exactly do those files need to be placed after they're unzipped?

Place them in the same folder as where you installed sumatra pdf. Then register the plugin from the command line with:
regsvr32 npPdfViewer.dll

regsvr32 npPdfViewer.dll

That is probably the best way. However, I went to %appdata%\Moonchild Productions\Pale Moon\Profiles\[randomstring].default\ , created a \plugins\ folder, and dropped the npPdfViewer.dll in it.

With that, it's just giving me "Error: SumatraPDF hasn't been found!" when trying to view a PDF in the browser.

Do you have the full 64-bit SumatraPDF otherwise installed already? Have you gone into Options/Applications and told Pale Moon to use the plugin for PDFs?

Yep.

[ehrbar]

Huh. No idea, then.

Maybe we can troubleshoot it. Just to recap, I've placed the npPdfViewer.dll file inside of the "AppData\Roaming\Moonchild Productions\Pale Moon\Profiles\[profile].default\plugins" folder and installed version 3.1.2 of SumatraPDF (the 64bit version) using the latest available installer from their website. Is that what your setup pretty much looks like?

Maybe we can troubleshoot it.

I think I got it working! HaleSun's trick worked. I'll test this out on my other computer, and if it works there, it might just be time to upgrade to Pale Moon 27 on the main machine .
