PDF reader recomendation?

[ppppenguin]

I've got 64 bit Irfanview and the set of plugins but it still won't open PDFs. Says it can't load Ghostscript. Looking at what Irfanview says it has installed as plugins, the list includes POSTSCRIPT.DLL which says it's for Ghostscript formats including PDF. In "Properties/Settings under PDF plugin options the box to "Use (new) PDF.DLL" for PDF loading (otherwise ol (old) Ghostscript plugin will be used)"

PS: Just looked at Properties/Settings Postscript options and ticked the Custom path box for Ghostscript location which was defaulted to: C:\Program Files\GS\Bin\gsdll32.dll
It works.
