    error message missing AppvlsvSubsystems64..dll

    None of the options worked. I still get the same error message w.hen I try to install the new software. Is there a place I can get AppVlsvSubsystems64.dll and add it to my computer?

    Thanks,

    Mike

    AppVlsvSubsystems64.dll keeps disappearing since update

    Ever since the "new" Windows 10 update hit I have had to reinstall Office 365 about five or six times. I keep getting an error box that says AppVlsvSubsystems64.dll
    is missing. This is becoming quite irritating! Anyone know how to prevent this, or at least a shorter fix?

    AppvlsvSubsystems64..dll missing

    Hi

    I had to have a new hard drive installed on my computer which I picked up my laptop yesterday. This morning I reinstalled My Office & now I'm trying to open a Word document. I am getting this WINWORD.EXE -System Error The code execution cannot proceed because
    AppVlsvSubsystems64.dll was not found. Reinstalling the program may fix this problem. I did reinstall My Office which didn't fix the problem.

    I followed the instructions given to another user. Here are instructions:

    From the description provided, I understand that you are unable to install any application/program in Windows 10. Let me assist you to resolve the issue.

    As an initial recommendation, I suggest you to Unregister and re-register the Windows Installer. Follow the below steps.

    a) Press the ‘Windows + R’ key on the keyboard to open the Run Command dialog box and type MSIEXEC /UNREGISTER, and then click OK.

    b) Click Start, click Run, type MSIEXEC /REGSERVER, and then click OK. Even if you do this correctly, it may look like nothing occurs, or you may briefly see an hourglass. After you run this command, the operation is complete.

    I only get as far as step a) no dialog box appear to continue to step b). What am I doing wrong?
