electron-builder: Download block maps Cannot download differentially, fallback to full download - Windows 10 - Github Private -Error: Maximum allowed size is 50 MB

Faced with the same problem(

"electron": "7.1.2",
"electron-builder": "^21.2.0"
"electron-updater": "^4.2.0"

why this issue is closed while so many people feel hurt(

Its still happening for some users, its a issue pretty common for electron updater, after years its still happening, will it be ever solved?

I’m on “electron-updater”: “^4.3.9” and “electron-builder”: “^22.13.1” And got: Cannot download differentially, fallback to full download: Error: sha512 checksum mismatch

Been facing this issue for a long time. I’m also baffled why this has been closed multiple times when people still have the issue. I don’t see any resolution on any of the issues either.

I’ve tried with at least 3 different major versions of both electron and electron-builder/updater, as well as many different minor versions. Nothing seems to fix it. Note, it works fine most of the time with a public github repo, although I’ve run into the issue using a public before. It seems the main issue is with private repos.

Can somebody please provide some sort of answer to the problem, or possibly an insight as to what is going on?

Currently on

"electron": "^9.2.0"
"electron-builder": "^22.8.0"
"electron-updater": "^4.3.4"

22.11.1 was released two days ago as a pre-release.

But this size error still exist nothing changed

New version 1.0.9 has been downloaded to C:\Users\MJ\AppData\Local\hairpin-admin-updater\pending\update.exe

The same problem, but the file downloaded

This is weird, so I build my program with the following dependencies “electron”: “^5.0.13”, “electron-builder”: “^22.3.2”

by downgrading electron version and auto-updates working on windows

• Only working auto-updates on windows if the repo is public If I make my repo private it doesn’t work.

The latest electron 8.0.0 building the app doesn’t work auto-updates. for windows.

I’m on “electron-updater”: “^4.3.9” and “electron-builder”: “^22.3.2” And got: Cannot download differentially, fallback to full download: Error: sha512 checksum mismatch

Not sure its because if my application is on the old version of elec updater, and this is the new one, but I don’t know how to compress my app, it’s about 7mb over… this is a pain.

This is still happening.

You should use the latest “electron-updater” package: "electron-updater": "^4.3.4"

Do we have a fix for the said issue? Somehow, I temporarily managed to solve the issue by making changes to the library. This has resolved my issue.

• Go to your node_modules folder and search for “builder-util-runtime” package
• In the “out” folder look for “httpExecutor.js” file and somewhere around line#240, comment out the following three lines.
• Build a package and publish it via Github private repo.
• To check if the issue is resolved, publish a new version again and see if the download works.

The above steps solved my issue and a new log “main” file gets generated for the latest version.

Screenshot of the above steps:

In the source code packages/builder-util-runtime/src/httpExecutor.ts 中，line 209 has the following code:

              if (size > 52428800) {
                callback(new Error("Maximum allowed size is 50 MB"))
                return
              }

It seems that it only works on xxxxx.exe.blockmap，For differential download, you can try to delete it. When electron-updater cannot find it, it will use full download. At this time, the application should be able to update normally.

The difference download seems to download only the parts different from the history version, which will be very fast, but if the difference is > 50m, it is no different from full download.

hope that can help you
