I have avast premier installed on my Asus laptop (windows 8.1, 64 bit, core i5, 8GB).
This is what I do to install Bitdefender (but did not work)
1. I have removed avast premier using avastclear.exe in safe mode and restarted the computer
2. start bitdefender_tsecurity.exe
3. A pop-up window appears with the message: "Welcom to Bitdefender. Before continuing, we need to remove any other antivirus solutions." I clicked continue, and nothing happenned.
Important points:
1. I have no other antivirus solution on my computer.
2. I could install Bitdefender total security on my other computer running windows 8.1 and with avast premier removed as above. That computer is not ASUS.
Anybody has any suggestion? I have been trying the whole day and still can't figure out why it did not work. The installer issue no message; it just did nothing.
