Main Threads:New version of Backupper refuses to install
  • I had a previous version of Backupper on my Windows 7 machine. I uninstalled it before trying to install the new version. As part of the uninstallation I restarted the computer as instructed. Next I tried to install the new version, but after the first screen or two of the setup it displays a message saying "Setup has detected a restart required to perform the uninstall. Please restart and try again." I restarted again...and again....and again. Every time I try to install the new version it gives me that same message and won't let me continue the installation. I have also tried re-installing the old (2012) version to see if that would work, but it gives me the same message.

    What can I do?

    Thanks in advance for any suggestion.

  • I’m sorry to hear that this problem happened in your computer. 

    It may occur that our uninstall procedure cannot start normally in your computer circumstance. 

    To solve this problem, you can directly delete the installation directory of AOMEI xxx and then delete its registry. 


    Steps: 1. Find and delete the installation directory of AOMEI xxx

    2.Go to Start, enter and run regedit. (Note: you should run it as Administrator) 

    3. Locate the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Aomei Partition Assistant_is1   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Aomei Partition Assistant_is1

    and then delete this folder. 

    4. Finally, you can install the latest version. 



    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\AOMEI Backupper


    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\AOMEI Backupper





    delete these and the installation directory.

  • Thanks for the help. It finally allowed me to install it. After following your instructions it still said it "detected a restart required to perform the uninstall" at first. But then I searched for "AOMEI" and "Backupper" in regedit and deleted every folder or key that had one of those words. I kept searching until it found no more, and then the setup allowed me to install the new version.

    In case anyone else has the same problem and reads this in the future, if regedit says you can't delete one of those registry folders that were mentioned, you might have to manually edit the registry permissions to allow you to delete them. That's what I had to do, and I used the instructions at

  • Thanks for the support you provided.

  • Hello,

    I have exactly the same problem: uninstalled Aomei Backupper free version 3.6 (I think), and when trying to install new free version 4.0.6 the installer refuses saying I should reboot, but after rebooting the installer always says the same.

    I've deleted the keys of AB in the registry (not only the specified above by admin message, but ALL, as user OneWhoBacksUp had told) but the problem persists.

    I've also deleted AomeiBR directory in c:\ProgramData\.

    Currently I have neither Aomei directories nor Aomei registry keys (hadn't installed other Aomei products) in my Windows 7 but the installer still refuses to install the last Backupper.

    Any ideas please? Thanks in advance.

  • @mrband  Please use a registry clearer to clean the registry information and then install Backupper again to see if it works.
