msi package cannot be installed

When I try to install any msi-based program (in my case VirtualBox but also 7zip) I get following error messages: "the system could not open the specified device or file." and then "the installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2755." when I hit the "install" button.

I have captured the most verbose log I could get and posted it here: https://pastebin.com/PZSRQgwy

It seems that the installer is unable to read the msi file.

What I have already tried:

  • rebooting
  • re-registering msiexec with msiexec /unreg and msiexec /regserv
  • sfc /scannow
  • this troubleshooter: MicrosoftProgram_Install_and_Uninstall.meta.diagcab
  • give everyone full r/w permission to the msi file and parent folder

I run win 10 home build 1809 with all available updates

my av is avast

I have no clue what could have coused this error because a month ago it did work

Windows for home | Windows 10 | Install and upgrade

    The issue has worsened.

    Even the default admin is unable to install msis.

    Avast is not the reason, I tried complete uninstalling but the issue persisted.

    Does anybody have additional ideas what to do (without reinstalling windows)?

    Yesterday it worked with the default admin account, today it doesn't anymore.

    I found this thread in the avast forums, and their solution with disabling hardware acceleration in the troubleshooting area worked.

    Open Avast -> menu -> settings -> general -> troubleshooting -> uncheck "hardware virtualization" checkbox -> reboot

    Hi olit2000

    My name is Andre Da Costa; an Independent Consultant, Windows Insider MVP and Windows & Devices for IT MVP. I'm here to help you with your problem.

    Start by uninstalling Avast then try again.

    Sounds unlikely, but Avast is notorious for interfering with stuff it should not in Windows 10 and I honestly recommend users not use it either. The built in Windows Defender Security is more than sufficient protection.

    If you wish to not do that...

    Could you confirm if this also happens in the default Administrator account?

    Open Start

    Type: cmd

    Right click CMD

    Click Run as administrator

    At the command prompt, type:

    net user administrator /active:yes

    Hit Enter

    Close command prompt, restart, then try signing into the Administrator account.

    Try running the file again.
