Hi,
I use creative cloud Adobe DC and the reader however I have to wait up to ten minutes sometimes to view a pdf and now its updating my pdf reader 2018 without my permission, so I cant instantly open PDFs anymore(the logon process is tedious and time consuming). This changes the default and ruins my ability to open PDFs.
I was wondering if I could set Sumatra as the default in IE11 as it's light and fast!
cheers
Nik

All reactionsSumatraPDF only worked with Firefox derivatives and currently only fast 32bit browser I can use is Palemoon and for 64bit I can also use Waterfox classic. So short answer is generally the legacy support for SumatraPDF plugin is very limited to those 3.

All reactions Something went wrong. Quote reply Sep 17, 2022Why oh why doesn't Sumatra, like virtually every other modern app that opens particular file types, include a setting to make it the default PDF reader? I've found no way to make such a setting in Windows. From Windows' viewpoint, it's as though Sumatra doesn't exist. Microsoft is apparently intent on keeping PDFs opening in MS Edge. It's ridiculous.

All reactions Something went wrong. Quote replyCorrect Firefox, Foxit, Others and even Adobe have had to devote teams to overcome the way MS keep moving UAC settings, the silly point is the encryption for User preferences is fairly simple to circumvent so MS retrigger(s) Edge as dominated PDF default. A clean reset Adobe is about 150 registry settings ! but primary entry can be seen with
REG QUERY HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf\UserChoice that should show MSEDGE as UAC application
The best way to reset is USER select ANY PDF press ALT/Enter OR right click PROPERTIES then change the "open with" then ignore Edge and other old assignments including ignore any SumatraPDF icons as potential old entries keep move down to select always open AND LOOK for another app on PC then pick the EXE you want e.g. either in %localappdata% or %programfiles% sumatrapdf e.g. which ever has the desired sumatrapdf.exe now if you check you should see similar to
> REG QUERY HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf\UserChoice HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf\UserChoice ProgId REG_SZ SumatraPDF.pdf Hash REG_SZ ugfTZgIpvT8=
the problem is the Hash can change each time so as example resetting
ProgId REG_SZ MSEdgePDF Hash REG_SZ **2YAsaliqJuU=** ProgId REG_SZ SumatraPDF.pdf Hash REG_SZ ugfTZgIpvT8= ProgId REG_SZ MSEdgePDF Hash REG_SZ **Tn9SNtvdjd4=** thus varies each time
there is an exe and powershell script that aims to reset by hashing and it is interesting that the SFTA tool uses SumatraPDF as an example (this is NOT a proposal or endorsement just illustration of typical use)
