Installer Issues - "installation package could not be opened"

I’m making a post on behalf of a user who contacted us with an installer issue they were running into.

When trying to run the Veras installer for windows, this error was encountered:

I’ll post more details as I have them, and I’ll add our initial troubleshooting suggestions below:

It seems like the installer file may have been corrupted. Can you try deleting and then re-downloading the EvolveLAB_Veras_Setup.msi file from our website:

After re-downloading, if it still doesn’t run, can you right click on the installer file, select Properties, and verify the following information:



  • checking the file sizes makes sure that you have downloaded the entire installer file, and that the download processes wasn’t corrupted or interrupted.
  • checking the Subject on the details page verifies that you are using the latest Veras installer, version 2.0.5.0 at time of writing.
  • checking the signature details, and makings sure the name, signing time, Issued to, Issued by, and valid from information is correct ensures that you are using our valid signed installer, and not a potentially malicious copy

If any of the above details are different, please let us know!

If it still doesn’t work, can you let us know what version of Windows you are using?

Ok one more suggestions:

  • make sure you have admin rights for your computer. Try right-clicking on the installer file, and selecting Run as Administrator
