Windows Installer Error

Question

I'm using Windows 10pro and trying to install a new program and keep getting the error:  

"This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package".

Answer 1

Hi, This is Ramesh.

Please redownload the .msi package and save it to the C drive's root directory. Then, open an admin Command Prompt window and run the installer package using the following command-line syntax:

msiexec /i "C:\filename.msi" /L*V "C:\msi.log"

(Replace filename.msi with the actual file name of the setup package.)

Example:

msiexec /i "C:\VB60SP6-KB3096896-x86-ENU.msi" /L*V "C:\vb6redist.log"

Let me know how it goes.

Answer 2

The error message you are encountering, "This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package," can occur due to several reasons. Here are some common causes and resolutions:

1. Package Not Found: Ensure that the installation package is located at the specified path and that you have the necessary permissions to access it. If the package is on a network drive, make sure you are connected to the network.
2. Unsigned Package: The package may be unsigned or improperly signed. Check if the package is signed and that the signing certificate is valid.
3. File Corruption: The installation package might be corrupted. Try downloading the package again or obtain a fresh copy from the vendor.
4. Windows Installer Service: Ensure that the Windows Installer service is running. You can check this by typing services.msc in the Run dialog (Win + R) and looking for the Windows Installer service.
5. Compatibility Issues: Verify that the package is compatible with your version of Windows. Some packages may not support certain versions of Windows 10.

If the issue persists, you may want to consult the application vendor for further assistance or check for any specific requirements related to the installation package.
