One:
I have AIDA64 set to check for new versions, including betas.
I received your mail-outs regarding v5.7 yesterday and today, but I had to manually download the latest 5.7 version.
Two:
After downloading the new version, I exited AIDA64 and started the install, but got the following error.
I suspect it may be related to Windows Services.
I then turned off auto-start with Windows and rebooted... install went fine.
