Missing Python Runtime (search)

[Peter]

The version check fails all the time. Like there is a code that would parse the output and check the version.
But it just fails for some reason...

TY! Installed. New logs after 2 successive tries to get Search bar enabled:...

Not running cmd as an admin. Only difference is running it through task manager or through start menu search.

Reading your other comments next!! By now I have removed both Python 3.10.11 and 3.12 with iObit. And I have rebooted.

Currently, according to iObit I have both Python 3.8.10 and the launcher. I will do another Python 3.8.10 setup and post the new logs next.

EDIT: ran 3.8 setup twice: once to remove it completely, once to install it

Trying again with your latest custom qB version:



I now get an elevation prompt to run the full Python setup:

The search bar still isn't available and Python still isn't found.

SO... Python 3.8 isn't found while just having been installed! This is so frustrating! :)

I think it's safe to conclude it's a problem with my system now? Not qB? Still open to suggestions! :)

TYSM!

I went back to the registry. I somehow deleted the whole Python branch instead of the 3.10 and 3.12 hives.

It isn't looking good: no registry entries are found for HKCU!



Permissions seem okay!


And HKLM now seems okay too...

Something about your system is not being liked by this Version check... I mean I could just give you a "fix", but we are trying to get to the bottom of this.

What system do you use? Windows 11 Pro?
What's your system language?
Are you the only user on the system?
Do you have UAC disabled/changed?

I have 1 other local account for a security camera. I have a local user account, not a Windows Cloud account.

Of course not!

Avast on or off doesn't make a difference neither.

Ok 1 sec I'm working on another build..

: ) awesome. I did another 3.8 setup but HKLU Python keys are not recreated

[Peter]

Yeah I tried to edit the way version.h works but no dice.
So it's a bit tough.

On Windows, sadly, the application will not run from terminal so to speak. It won't output anything.

There are a few qDebug() calls scattered through the code, but qDebug() is very hard to intercept. There are third-party apps that let you try, but I didn't have much luck with them. Only a few message came through.

And messing with version.h directly would break the asserts it's using.

I suppose this will turn into a ticket.

You can link this thread too. I think it's the version.h misbehaving for some reason. But that file is beyond me.

You went above and beyond... I'll stick around and see what GitHub says... Once more, thank you very much! And I love having my custom build now ;p

A small and weird update...

qB, with lots of torrents seeding, for me always was an often not-responding piece of software. In the end, it'll catch up and start responding again. I always took that as a given and on face value.

The custom build you shared with me was especially troublesome. So troubling and freezing so often, I installed the official build again. I had a few freeze-free days and I was really surprised how smooth it worked, and how horrible your extra logging impacted performance previously.

Today, I updated to v4.6.0 and quickly had trouble again. Sorting on Date Added or other view changes immediately had qB freeze again and I'd have to wait a while before it became responsive again.

That got my attention. What the frack is going on??

Right after updating to 4.6.0 I once more tried the View... Search bar. This time, I got a full installation of Python 3.10.11. This surprised me, I don't remember removing Python. But okay, whatever. Worse was that the qB program hangs were back again.

Which triggered me enough to start iObit uninstaller and remove everything Python related once more. After it was done (I still had qB running) I did a new search for installed programs and iObit found 1 left over Python installation... Huh? It was 3.10.11. So I quit qB, did another iObit removal of Python and this time around it indeed was removed and a new search found no Python left on my system.

I once again started qB and... It once more stopped freezing!

SO, to conclude... While View... Search bar keeps triggering a Python 3.10.11 installation and apparently fails to find it no matter how often it installed / repaired Python 3.10.11, qB indeed does use Python 3.10.11 once installed! Why else would it become so unresponsive to any sorting action or torrent Force Check etc. Remove everything Python and qB works like a charm. Install it, have qB not find the installation and have it freeze again.

Like I said... Weird shit. I think I'm just gonna do a fresh installation and move everything to a new installation. Sigh.

Peace!

Can't you purge Python and grab the latest 3.8 or 3.9 version from Python's website? Just to test..
(also make sure to log out and log in once you reinstalled python so Windows can see the new PATH)

Never mind, it's as unresponsive again as your custom build appeared to be :(

But for real, for a few days my qB was smoooooth :)

Will do! But it's an utter mess atm. I even discovered qB has crash reports... Never had those. It's really choking on a few big torrents (300 to 400GB), even forgetting about them a few times.
