FX changesets as reference: https://hg.mozilla.org/mozilla-central/rev/af88a04128f6 https://hg.mozilla.org/mozilla-central/rev/86a19f0dfa67

This is a simple port of the FX patch. Jörg, I know you are not a installer specialist. But do we have one? I have nothing added, only ported. Aryx, can you check all is okay? Thanks.

Error message on XP. By clicking on "Ok" I get the system requirements page of TB 45.5.0. But in FX bug there was the page of FX 50 and not 53. So this should be okay.

Forgot the link to try build for the installer: https://treeherder.mozilla.org/#/jobs?repo=try-comm-central&revision=a1588d0c9330a2a5b9f2aabe96765ad93de68da8 The orange is because of check-sync-dir.

Comment on attachment 8813369 [details] [diff] [review] noXPInstaller.patch Review of attachment 8813369 [details] [diff] [review]: ----------------------------------------------------------------- Philipp (:Fallen) is build peer, I don't know whether that covers installers. I checked that you merged the two FF changesets correctly. I would be good to actually try an installer ;-) r=jorgk.

You can find the installer from the try build: https://archive.mozilla.org/pub/thunderbird/try-builds/richard.marti@gmail.com-a1588d0c9330a2a5b9f2aabe96765ad93de68da8/

Comment on attachment 8813369 [details] [diff] [review] noXPInstaller.patch Can test the Try installers tomorrow (on XP).

Thanks, I'll try a Daily installer later today. I hope we get more feedback from Sebastian.

I tried the installer on XP. The screenshot (attachment 8813371 [details]) is from this try.

Thanks, attempt to install it on Win XP created the same popup like in comment 10.
