Wouldn’t be a nice feature for the update server to return a dedicated message ? Like :
« Your version need a manual update. »
or
« Notepad++ 7.6.4 available. The automatic update has a problem. Wait few days or do a manual update. »

yes and no.

« Your version need a manual update. »:
this might confuse non power users, probably leading them to believe, that there is something wrong at their current setup or current notepad++ version, requiring a manual repair.

« Notepad++ 7.6.4 available. The automatic update has a problem. Wait few days or do a manual update. »:
this contains the word “problem”, probably leading them to believe, that there is something wrong with the update servers, or worst case, a problem at their current installation, eventually leading them to conduct unnecessary “fixing” steps.

i agree with the developer’s current choice, to omit any further explanation at the updater, as soon as a reason is found to delay or suspend an update.
all technical information about any delay can be found here, if interested admins or power users like you, discover a newer release, and want to know more about it, or why it is currently suspended as an automatic update.

please keep in mind that there are millions of regular notepad++ users all around the world, and dealing with an elevated amount of repeated supportive questions, triggered by a potentially misleading updater message, will be very difficult for the solely volunteering community members and the volunteering developers.

thank you for your technical interest.

two of the main reasons are:

• versions 7.6.1 to 7.6.3 deliver a wrong query to the update servers and have caused a permanent update loop while testing.

• version 7.6.4 has a little glitch regarding unsaved tabs. if you conduct e.g. a search in all opened documents, and you double click on a result that is on an unsaved tab, it will prompt you with a save dialogue.

for now the update is reportedly scheduled for the next 7.6.5 release, if no issues are found, which would cause more support than benefit.

currently the online update is suspended until version 7.6.5 for technical reasons.

if you want to update your notepad++ to 7.6.4. 32 bit manually, please download the installer from here: https://notepad-plus-plus.org/repository/7.x/7.6.4/npp.7.6.4.Installer.exe and install it over your existing version 7.6.3.

note: do not uninstall 7.6.3. before running npp.7.6.4.Installer.exe.

Could you please fix this?

Maybe it is not broken. Maybe it is by-design. Think about it.
