Windows7 installation error 54

Hi guys!
After a fresh install of win7 ultimate 32-bit i tried to install the brave browser as i was using 1.15.76 before but i keep getting installation failed error 54?
So i looked up some older versions and tried again but got the exact same error number again after the download and installation?

The older version i picked was from may 2020 as id also used an older version on another fresh install before the 1.15.76 version i was using last time.

Any ideas where the error 54 comes from and what causes it?
Im guessing the latest version of brave does not work on win7 ultimate 32-bit & because that failed it also caused the older version i downloaded and tried to install too fail aswell?

Thanks in advance for any suggestions!


Any text in the error message?
Something like “The Windows Installer Service could not be started/accessed/whatever”?
Or could it be a permission error, e.g. the windows user has no permission to install?

Otherwise, if that is ruled out, can you please try the following:

  • If you absolutely need to keep using the old version, stop here and don’t do what I say.
  • If you have BATs you don’t want to risk flying away, stop here and don’t do what I say.

  • Make a copy of the Brave profile folder
    (it’s somewhere in Application Data, not sure where exactly but I can look it up if you need)
  • Download the current release for Windows 32bit.
  • Try to install it.
  • If it works, good.
  • If it still errors out, post either screenshot or exact text of the message.
  • If you manage to, try identify which process errors out
    (I guess it should be something like MSI, Microsoft Installer, Windows Installer Service)

As far as I know, Brave supports Windows 7 32bit.
It shouldn’t be necessary to use an old version, and it’s generally inadvisable.
The system requirements page says:


  • Windows 7, Windows 8, Windows 8.1, Windows 10 or later
  • An Intel Pentium 4 processor or later that’s SSE2 capable

If those requirements are met, it should work.

edit … notices it’s 3 months old … oh well.
