qBittorrent is an open source BitTorrent client, cross-platform and free and an alternative to µTorrent. It is written in C ++ based on the Qt toolkit and is developed by volunteers. However, several users report that they are receiving the message »An E error occurred / S” O “E error / S”: permission denied “. This error will stop your download and then you will need to start it / stop it again manually.
What causes the E error / S para qBittorrent?
We investigated this particular issue by looking at various user reports and commonly used repair strategies to troubleshoot users who were in a similar situation.. According to our research, there are several different scenarios that are known to trigger this particular error message:
-
No permission for custom download location: there is a possibility that the problem is due to a permission access case. If the download location is changed from default to custom, then qBittorrent might need read and write permissions on that location. Several users who are in a similar situation have reported that they managed to solve this problem by running the application as administrator or keeping the default location for download.
-
Windows defender interference: Another possible case where this error occurs is when Windows is using Windows Defender security system to keep your system safe. Since the security system stops any kind of harmful or untrusted file, it may be able to interfere with your torrent files and cause them to stop working.
There can be many other unknown reasons for E errors / S in qBittorrent due to other programs or devices. But for the most related and common, listed below are those that are related and have been resolved.
Method 1: Run qBittorrent as administrator
As some users have reported, open qBittorrent by selecting the option “Execute as an administrator” has the potential to solve the problem automatically. Because when any application is run with the Run as administrator command, the system can accept that the program is safe to execute any of the administrative commands. This also helps qBittorrent with the necessary permissions to access different storage locations. To open qBittorrent as an administrator, do the following:
-
Find qBittorrent in the start menu (press windows + S to start the search bar).
-
Right click on qBittorrent and select Run as administrator
-
Confirm the User Control warning as »Yes«
-
Now check, if you get any error from E / S.
Method 2: disable Windows Defender in Windows 10
Some affected users, who upgraded their windows from the previous version to Windows 10, They were able to solve your problem by disabling Windows Defender and installing a third-party antivirus. And disable Windows Defender in Windows 10 it's relatively more different than what you would have had to do in Windows 7, 8 u 8.1. You can disable it in two different ways; one is temporary deactivation and the other is permanent deactivation of Windows Defender.
The temporary method will use the conventional start menu, in which Windows will reactivate Windows Defender in a couple of days. And the permanent method will be in your computer's registry editor. We are going to make the method permanent and install a third-party antivirus, which can replace Windows Defender work.
-
Open Run by searching or pressing the buttons (Windows + R) on a keyboard
-
Then type »regedit» in the text box and enter
-
Look for WinDefend in Registry Editor in the following directory:
HKEY_LOCAL_MACHINESystemCurrentContolSetServicesWinDefend
-
Next, right-click on »Start» and select Modify
-
Here you have to change the value data to “4”
-
This will disable Windows Defender permanently unless you enable it again in Registry Editor. Now start the qBittorrent client and see if the permissions issue is resolved.
