1.25. "Error 1935. An error occurred during the installation of assembly ..."

Disponible en español: "Error 1935. Ocurrió un error durante la instalación del ensamblado ..."

Applies to: All releases 6.x/7.x

When I try to install Palisade software, I get the error message

Error 1935. An error occurred during the installation of assembly component

followed by a long code in { } braces, or

Error 1935. An error occurred during the installation of assembly

followed by a Microsoft product name, such as Microsoft VC80.CRT.

This happens occasionally, and for most people the cure is simple:

Restart Windows (Start » Restart, not just logging off and on), then right-click the installer and select Run As Administrator.

Try installing Microsoft components manually:

If the install still gets Error 1935 after the Windows restart, probably there was a problem installing one or more of the Microsoft components that are included in the installer. These components are listed in Microsoft Components Required for Palisade 6.x Software Install or Microsoft Components Required for Palisade 7.x Software Install. Please install them manually, in order — but read the notes for each one because some may not apply to your situation.  (You can skip the installs of Project and SQL for now.)

If the Microsoft components all install without error, re-run our installer (again, Run As Administrator). It will sense that the components have been installed and will not try to install them again. This should get you past the problem and allow our software to install.

If one of the Microsoft components fails to install, do not go on to the next component. Instead, you will need to fix the problem that prevents it from installing. If a Microsoft component doesn't install, there may be some problem in your Windows installation. You can try to repair it from your Windows install disk, if you have one, or by following this procedure:

  • Click the Start button and type cmd in the search window.  You should see cmd.exe at the top of the results, or close to the top.  Right-click it and select Run As Administrator.
  • In the Administrator window that opens, type this command: sfc /scannow

After SFC finishes successfully, close the window and then retry the Microsoft component install that failed.  If SFC fails, or if the same Microsoft component still will not install, please ask your IT department for assistance because this is an issue in your installation of Windows.

Windows Insider:

One customer (as of this writing) got Error 1935 because of a bad Windows update. He was in the Windows Insider program. No solution worked until he got a later update that fixed the problem.

If you're a Windows Insider and have Error 1935 on installation, and the above solutions don't work for you, make sure your Windows updates are current. You may need to wait until Microsoft releases an update that fixes the problem.
