Will not download - I can download RouterOS 3.30 or RouterOS 5.0rc5 but not RouterOS 4.15, torrent will not start and getting “http://download.mikrotik.com/netinstall-4.15.zip - 404 - Not Found” ??
What mirror? For me is USA and other ok
That is symptomatic for MT development - release a new version to release another one shortly to fix previous release.
I see lack of testing here. Also, once and once again why does not release notes list all changes?
Upgraded from 4.14 to 4.15 on RB450G. Upgrade seemed to have failed, router simply never came back. After 17 minutes I pulled the power and then plugged back in. Router seemed to boot up just fine with new 4.15 version after that.
Are we SURE the 4.14 boot loader bug didn’t affect other models?
The links are dead for this HTTP download (combined package) from the Mikrotik site. They must have found a bug… Although my email this morning from Mikrotik says 4.14 is now released, but on the website says 4.15?
I tried to upgrade from 3.30 to 4.15 and it told me my license was invalid so I reverted back and all was well. Why did it do this? I’ve never had this happen before. I tried to update license but that failed as well. Anybody have an awnser. Thanks
Never mind found the answer farther down the forum.
you put the package into the wrong folder. FTP it to the root directory, and if you drag files from desktop, drop them into the FILES window, not Packages

yes we are

No, the links are working (see above responses). If not sure, always use torrent download. It works.
Although my email this morning from Mikrotik says 4.14 is now released, but on the website says 4.15?
v4.14 was released ~12 hours earlier, you probably didn’t check email during that time.
I can’t get any of the link working including torrent. Are the files removed?
works fine for me, and other people.
Not for me, too… 
This isn’t the first build thats been an emergency show stopper of a bug with RB’s, How does something like this get past QA?
I feel sorry for whoever the user was that found this and had his config wipped, It took 60 hours post-release to release this information to the rest of us

yes we are
433ah
i have bug boot loader 4.14 and 4.15
The download links are valid now. Thank you!
IF this happens again: when you click on the link, DNS load balancing makes sure you get a different server every time. If you happened to get a server which didn’t finish updating it’s files yet, you got a 404 error. Just refresh and try again, you will get a better server. We are making the system a little different now, so that the server is not offered if the files are not there yet.
Mikrotik,
I thought we had this discussion before? Did you get the memo?
Sorry about that. The problem was with one specific RouterBOARD model, and not after upgrade - only after Bootloader upgrade. So the problem is not in RouterOS, it was with the RB1000 bootloader that RouterOS included. The problem did not affect RB1000 users that didn’t upgrade the bootloader.
Hello,
I’ve just upgraded my RB433 from 3.30 to 4.15 and after installation when I open my RB in Winbox I got this message:
ROUTER HAS NO SOFTWARE KEY
Your router does not have any valid key.
Please, get valid key from > http://www.mikrotik.com
and enter it at “System | License”.If you already have paid for this license, please,
press “Update Key” in “License Window”Router will stop functioning after 23h and 40m if no valid key is entered.
I’ve tried System > License > “Update License Key”
But in status I get: “failed: Invalid request received!”
email support with your supout.rif file to solve the key issue
Please check…
