Added a key ("folder") SupportedTypes under Computer\HKEY_CLASSES_ROOT\Applications\mupdf.exe - then added a new "String Value" for this key, which I renamed.Checked Computer\HKEY_CLASSES_ROOT\Applications - it had an entry mupdf.exe, that is: Computer\HKEY_CLASSES_ROOT\Applications\mupdf.exe.Checked Computer\HKEY_CLASSES_ROOT\.pdf\OpenWithProgids - it had a key named MuPDF.Here is what I did (after several times opening via Open With/Choose another app/More apps/Look for another app on this PC/(look for and choose mupdf.exe)):
pdf files however, this program was not "installed", I just copied the binaries to C:\bin. Just adding a few notes here - had a problem of trying to add MuPDF to the Open With list for. The NirSoft tools are freeware AND portable, so OP could easily & quickly give the above a try. also this other post Strange open with list (inconsistent with registry) mentioned by OP), but it's not excluded either. I'm not claiming that the same is happening in OP's case, as several elements of the "Open with" menu seem to behave bizarrely (see e.g. Next browse to the correct location, select the executable, and click "Open" button. Right click a pdf file > Open with > Choose another app (or "Choose another program." in Win7). "Open With" list by following the steps indicated already: correct path, also reflected by the tool's icon being shown), I was able to add it to the
Not only the most recent (and correct) one: somehow the obsolete name had also pertained.Īpparently, this erroneous/obsolete value was the first one encountered and withheld by other applications, which could explain the abnormal behavior ofĪs soon as OpenWithView displayed Nitro Pro correctly (i.e. With yet another NirSoft tool, MUI Cacheview (see ), which allows to "view and edit the list of all MuiCache items on a system", I found that the MUIcache contained several values for Nitro Pro. (I had changed a folder name in the path at some point, an was surprized to find it back in this overview)
Next doublechecking the application's path (that's another column in the same overview), I found that it listed an old path, not the current one.
Sure enough, it also listed Nitro Pro, but I became suspicious because the default icon of the tool wasn't displayed in the overview screen, whereas for all other programs it was. This tool lists "all available applications in the 'Open With' dialog-box of Windows". Trying out all kind of suggestions found online, I also gave NirSoft's OpenWithView a shot. That's on Win7, but it doesn't look like if MS' approach to the feature has changed between both Operating Systems. I had the exact same problem when I couldn't add Nitro Pro to the "Open with" Context Menu for *.pdf files. Once I've confirmed this though, I'll write up an answer. I have not tested yet to confirm that Microsoft has resolved this issue or if something else broke loose.
I also found list similar question: Strange open with list (inconsistent with registry)Īnd checked to make sure that PDF SAM has both entries suggested by the answer there, and it does:Ī little bit after upgrading Windows 10 to build 1809 I noted PDF SAM is now showing in the Open With menu.
So, we've figured out how to remove unwanted entries from the primary list, but not how to add wanted entries to it. Then I opened the registry to HKCR.pdf\OpenWithProgids and removed the Waterfox entry from there, and this indeed removed Waterfox from the Open with list, but it did not add PDFSAM to that main list:
I would be happy if Chrome, Edge, and Waterfox were simply not on that list of programs in the Open with menu, and I assume this would free up enough room for PDF SAM to graduate to the main list, but only Waterfox shows in the OpenWithList in the registry, and removing it does not appear to make any difference.įollowing the suggestions in the question linked in the comments ( Manually Add Program to Open With in Windows 10) I tried DefaultProgramEditor and it failed utterly. I have modified the registry to set PDF SAM as the 2nd option in the OpenWithList:īut this does not appear to actually change anything. How to customise the Recommended Programs list when choosing what to open a file with?.How do I remove default windows items from the "open with" context menu?.I have looked over these questions for help: I would like for PDF SAM to be directly in the Open with menu. To select PDF SAM I must click Choose another app and select PDF SAM there. When I right-click on a PDF and select Open with, these are the options I am given. I use PDF Split & Merge (PDF SAM) frequently, but don't want to set it as the default PDF handler.
