Update 6571 won't work

James, here's what's worked for others that I've suggested...

1) Reboot, just in case there are pending updates or something else in the background.

2) Download the ATIH Cleanup Utility 2016/2015.  Right click on it and "run as administrator" even if logged in as admin

3) After cleanup, reboot and boot into Windows in Safemode with networking

4) Disable AV temporarily

5) Right click on the full installer or v6571 (as downloaded from your online account) and be sure to "run as administrator" again

Hopefully all will be well

Normally, you should not have to go through this, but since you've hit a snang, hopfeully this smooths things out.  In the future, when updates are available, I would recommedn downloading the full installer from your account instead of upgrading through the app (it just has always worked this way for me without issue), and be sure to right click and "run as administrator".  Personally, I have not had to disable AV for installs, but is probably a good idea in your case since somethign is causing an issue and it's easier to disable then to try and find the culprit in most cases. 

I went to the Cleanup page but am told to disable the Startup Recovery Manager and then remove Secure Zone. But my screen is nothing like the one shown and I cannot find the "tools" where one does this.

  So perhaps the best thing is to wait until Acronis gets the bug out of the system. Obliging a user to go into the registry is a little iffy.

Hello

I have the same issue. I receive the message "Update failed" but no more specific information.

James & Paolo,

This problem with 'Access Denied' when updating to the latest version, is as advised by Bobbo previously, caused by files being locked on your system, most often by security software such as antivirus, antimalware, anti-ransomware etc.  The best method to overcome this is to perform a clean install of the Acronis software with your security software disabled temporarily.

Perform a clean install of ATIH 2016

First uninstall the program via the Control Panel (or use an uninstaller such as Revo).

Run the Acronis Cleanup Tool (link in my signature below), then restart the computer.
Note: The KB document for the Cleanup Tool refers to checking for entries in the Windows registry - I have ignored this step on the occasions I have used it with no detriment, though if making changes to the registry, I strongly advise either exporting the registry before the change(s), or create a System Restore point, or image the drive for protection.

Reinstall the ATIH software (download a fresh copy from your Acronis Account if needed or if you don't have the latest build version installer).  Run the install as an Administrator (right-click on the installer to take this option).
It is also recommended to suspend your security programs (antivirus, anti-malware etc) during the install as these programs can cause Access Denied errors for the Acronis installer program.

Note 1: If you have purchased an Upgrade version of ATIH 2016 you will be asked for two serial numbers during the install - one for 2016 and one for the previous version that the upgrade is based on, i.e. 2015.

Note 2: The cleanup tool will remove all your backup tasks and task history.  If you want to protect this information, then open C:\ProgramData\Acronis\TrueImageHome\ in Windows Explorer - this may be hidden on some systems - if so, go to the Folder option in the View pane and enable hidden files & folders).

Save a copy of the Database and Scripts folders to another location to restore back later.

Note 3: In order to restore the above folders & contents, you must stop all Acronis Services & Programs else you will encounter locked files in the Database folder.

Thanks for the detailed reply, but as indicated above, I don't really want to go messing around in the registry for an update. I will wait for the next one, hoping the installation bugs are addressed by Acronis.

James, there is no need to modify the registry manually.  The cleanup tools only advise to check for certain keys to make sure they are cleaned up.  I have personally never had an issue with those keys after using the cleanup tool and no one I've suggested running the cleanup tool on has ever responded that they had to either.  I don't even bother checking for them anymore.

Thanks for the kind reply. But there is still the problem that the screen shots accompanying instruction page on a clean uninstall does not reflect Acronis 2016, and I have no idea how to begin.

  Sorry for the bother.

James, the decision here is yours alone to make as to whether you want to go through the steps to perform a clean install of ATIH 2016 build 6571.  As you state that everything is working fine for you with the version you have installed, then go with the old adage, if it isn't broken, no need to fix it!

I doubt there will be more new builds for ATIH 2016 now that they have ATIH 2017 in Beta testing phase, unless they decide to fix some of the issues that have been reported back to development and that may need to also be fixed in the 2017 version before it goes on general release in the Autumn sometime.

I see that the page to the cleanup utility has been revised. Thanks for alerting me to it. And for all your other help.
