Battle.net installation hangs at 45% and then gives error

I can’t install Battle.net.

I had it installed, and it worked fine. Suddenly, one day, my World of Warcraft stopped connecting. I could log in, but all servers were “Incompatible” or something like that. I have tried several things (repair, clearing cache, etc.) that I found on forums. Finally, I decided to reinstall it. But after uninstalling, I could not install it again. I have tried several things to fix that as well. Again, in the end, I believed that I had to reinstall the whole Battle.net, so I uninstalled it.

Now I can’t install Battle.net. At first, it just hung at 45% and never moved from there. I have tried installing it a lot of times in the first two weeks, and later, had to leave this topic for over a month. Now, when trying again, the issue is similar, but it later gives me an error:

"We’re having trouble starting Battle.net. Please try again. If the problem persists, try restarting your computer.

More help: BLZBNTBTS0000005D"

Well, unfortunately, “more help” did not help. Neither did reading other forum topics with people having issues at 45%.

What I have already tried, most of which, several times and in combinations.

  • restarted my PC
  • restarted my internet (router was turned off for over a minute and turned on, also tried disconnecting the RJ45 cable)
  • flushed DNS
  • deleted all the cache I found
  • deleted all registry Battle.net files I found
  • tried using the administrator account
  • probably more, but I don’t recall it all at this point (most of these I tried over a month ago)

The result never changed (except for this error lately, earlier I believe it just stopped at 45%).
Frankly, I have already lost a lot of my WoW subscription. I tried a lot of different methods, but later, due to other obligations, I just did now have enough mental capacity to fight with the Battle.net installer, and chose other games.

I would like to try and go back to this topic. Please advise.

Did you actually turn off the PC so the Agent.exe will also restart?

I have the exact same issue since Wednesday. Literally tried everything in the assist articles, reddit tips, and google page one. Nothing, still hanging at 45%.

I checked with my ISP if there is an issue with the internet and they said that my modem is too old. But the internet works for everything except WoW. Can update you tomorrow if that fixed my issue…

Yes, I did. I use a “Shut down” (and not Sleep) option at the end of every day. So unfortunately, that did not help.

In my case, I have changed my internet operator several months ago (long before this issue occured for the first time), so I doubt my router is too old.
