Hi Rivers Eldridge.
Welcome to the Microsoft Community.
Your old msi file will not install. I sincerely hope that your software is still supported by Windows, and it might be more helpful to reply if you could indicate in your reply what software you are specifically trying to install. Until you know exactly what your msi file is, you can try some of the generic problem solving below:
First you need to make sure that the Windows Installer service is turned on, which you can do in the following way:
- Press Win+R to open “Run”, then type “msconfig” and click “OK” to open the service.
- Find the service called “Windows Installer” and right-click on it and select “Start”.
The application will write files on your hard disk, you may need to add administrator privileges for it to be able to open properly, you can use the following way to add administrator privileges for the application (pay attention to ensure that the software is safe software):
- Find the main program of your application, right-click on it and select “Properties”.
- Select the “Compatibility” tab at the top of the window.
- Find “Run this program as an administrator” at the bottom and check this option.
- Click “apply” to save the settings.
Now you can try to install the program. If you still can't install it, you can try the following way to install it using the command prompt:
- Open “Run”, type “cmd” in “Run” and press “Ctrl + Shift + Enter” simultaneously. “to open the command line window with administrator privileges.
- In the command line window, run the following commands in order, after inputting the need to press the Enter key to run the command. msiexec /package C:\abc\zxc.msi
( C:\abc is the path to your msi file and zxc.msi is the msi file name)
You should now be able to install the msi file.
