Can't install new version (4.3.4) ?

[AndroidDeveloperLB]

qBittorrent version and Operating System

Windows.
qbittorrent_4.3.4_x64_setup.exe

What is the problem

I try to install the app as it told me there is a new version.

What is the expected behavior

Should work fine like it always.

Steps to reproduce

1. Have the 4.3.3 version of the app (64bit)
2. Notice it says there is a new version
3. Go to the download page, and get the new one (64bit).
4. Try to install.

Extra info(if any)

This is what I get, even if I run as admin:

"Windows cannot access the specific device, path or file. You may not have the appropriate permission to access the item".

Just to check that it's not some weird web browser issue, I tried to open an installer of Android Studio (an exe file, just like in this case) :
https://developer.android.com/studio
Worked fine (meaning it started the installer and didn't have this error).

I usually get this error if I try to launch the installer from a networked disk (or VM shared disk). Try launching it from a local disk.

Scratch that. I now see the path at the top of the dialog. Supposedly it is launched from the local disk. Does the v4.3.3 installer show the same error?

What I say might sound silly, but when an AV program quarantines the file silently I've seen this error message.

It is worth checking if the setup file still exists in the download location.

What do you mean "exists" ? It is still there. I can check "properties" on it. I can delete it. I can restore it...

The issue seems to appear for some other installers, but not for some others.
Not sure what is going on, but as it happens not just here, I close it. I will need to investigate it further.
Sorry for the hassle

@showstoppre I think you are right. I think it's because of these settings on MS defender:

Why does it occur? What is the setting here that caused it (I disabled all and now it installs fine) ?
