Access Denied when updating

Thread needs solution

I am repeatedly getting 'Access Denied' when attempting to update ATI 2016. I have about 10 workstations with ATI. Sometimes the updates work fine. Sometimes the failed update works when tried later. I have at least one workstation where the update fails repeatedly.

I saw a post on this elsewhere in the forum describing it as a longstanding problem, but searching on "Access Denied" failed to turn up that post again.

Is there anything I can do to fix this?

The best way around this issue is to download the full ATIH 2016 latest build installer from your Acronis account and run this as Administrator rather than using the in-app updater which looks to be more of a web updater and therefore subject to any issues that might interrupt that update process.

No, it works exactly the same as upgrading from within the application, but you have more control by having downloaded the full installer separately and having the ability to verify the checksum for the file before installing.

Tried downloaded from my account. Got the same "Update Failed" message. :( I will follow the instruction on the "More info: Acronis Knowledge Base" link, collect the prescribed info and post either here or to the Acronis Customer Central.

If you are saying that the Update Failed using the downloaded full installer file, then it would suggest that there is an issue with the current installation that is contributing to the failure.

In that case, save a copy of the C:\ProgramData\Acronis\TrueImageHome\Scripts & Database folders then do a Clean install of the full installer.

To do a Clean install, first uninstall ATIH via the Control Panel, then download / run the Acronis Cleanup Tool (link below) as Administrator, restart the computer and then reinstall ATIH.

Finally stop all Acronis Services & Programs then restore back the Scripts & Database folders to bring back your backup task configuration and history information.  Note: the Scripts folder can be restored easily but Acronis locks the database folder if any programs / services are active.

I have followed your instructions and ATI 2016 is [re]installed. In addition to stopping Acronis services, I had to end several Acronis tasks via Task Manager. I guess your statement "stop all Acronis Services & Programs" implied that, but I didn't figure it out at first. Interestingly, when I checked the options on the configured backups, the Schedule was set to "do not schedule" on both. I had to re-enter the schedule frequency and times.

Uninstalling and re-installing has generally been my solution to such persistent issues in the past. We'll have to see the next time it needs to be updated if this all worked. This thread is a good tutorial on how it re-install without losing settings or backups. I'll hang on to this. Thanks.

Glad to hear that the main issue is resolved - sorry that I forgot to mention about needing to reschedule your tasks.  The schedule information is held differently via the Acronis Scheduler Manager process and I don't know of any way of saving / restoring that data.
