Thanks a lot for your reply. I have note done my reply as below.
Is this when you try to install Brave, or did you already install it and this is when you try to open it?
My reply: I have installed it several times and it happens after I install it and run.
What version of Windows are you on?
My reply: Windows 11.
My first impression is that whatever you’re opening (the installer, or the app itself) is either corrupt or has been tampered with. I would suggest re-downloading and re-installing if possible, but other things may need to be done as well.
My reply: I have downloaded several times from brave.com and installed and reinstalled it. Even I tried beta version too. Same issue.
Do you have antimalware software (such as Windows Defender) on your PC, and is it being updated?
My reply: Yes I have bitdefender. But I have uninstalled it then tried. But no change.
Please help me.
