FIX: PDF preview windows ERR: this file can't be previewed

[DeeJay]

fix adobe pdf explorer preview

install adobe reader 32 bit from
https://www.webforest.ro/dj/AcroRdrDC2300120064_en_US.exe
Reader DC 32bit!!

open adobe reader DC then go to preferences->general->enable Explorer thumbnail preview, click ok to save settings

open regedit
go to
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Classes\CLSID\{DC6EFB56-9CFA-464D-8880-44885D7DC193}

There should be an existing AppID value, incorrectly set to {6d2b5079-2f0b-48dd-ab7f-97cec514d30b}

Change the AppID value to {534A1E02-D58F-44f0-B58B-36CBED287C7C}

Now see if the same registry path exists but without the Wow6432Node part. If it does exist, make the same change as before. If it doesn't exist then that's fine and you can skip this part.

restart pc
