Unable to install nextcloud on Windows 11 BEX64 error

le1908 · January 5, 2025, 6:44pm

Hi Guys,

I am facing a quite strange behaviour on two of my Windows 11 machines. After installing (without any configuration!) the latest Windows client, the client wont start.

After investigation the issue I found that in my events:

Downgrading to older Versions of the nextcloud client does not help. So maybe there is an issue with the latest Windows 11 Image and the latest Nextcloud client:

What I did so far:

Reinstalled Nextcloud several times with many reboots
created a local account with admin privileges to test the installation → same behaviour
tried several older versions of nextcloud
tried the compatibility mode in Windows
asked Google, chatgpt & co

from: C0000005 error and troubleshoot - Visual Studio | Microsoft Learn

A C0000005 error is memory error. Specifically, a C0000005 error is an access violation error caused by a buffer overrun.

I could imagine there is some specific version is faulty… but your statement

makes me think there is an issue with your Windows installation. I would focus first on security feature like anti-virus, anti-malware, EDR and similar.

Thanks for the fast reply. The interesting thing is that it is a barely new installed machine. Only Windows defender in place. I will deactivate it and try it again.

Mornsgrans · January 5, 2025, 8:44pm

Check the disk health by
chkdsk /r /f C:
in the console as administrator. It will perform a health-check of the directories and repair inconsistences, if found any.
After reboot and finished disk check, do the same with command
sfc /scannow
executed as administrator, too.
This wil check the Windows system files for errors.

Update: Deactivating Windows Defender does not help

le1908 · January 6, 2025, 12:23am

Update, maybe Solution:

I was able to install the client now. But I still see some strange errors in my event log.

What did I do:

Uninstall Nextcloud
Remove several fragments from the registry which were not deleted by the uninstaller
Scan for all folders / config data → found nothing
Turn off Windows Defender
Restart doing the suggestions from Mornsgrans
Restart again
Install Nextcloud Client
Restart again
Looks good for now

Really strange. The machine is clean installed no problems so far.
