About This Issue

The 1603 error message occurs when the Windows installer cannot install or uninstall software with MSI package formats in Windows 10.

You should not get upset in advance, as this article will give you the opportunity to correct this situation and install or remove this or that software without any problems.

1. Delete Some Processes

Any background software can harm the Windows Installer. Disabling background software before installing the program can help get rid of the Msiexec 1603 problem. Also, close all open windows in the taskbar and all icons in the notification area.

To properly close background applications, do the following:

Press Win + X and select Task Manager from the menu, then open the Processes tab and close all software. Just right click on each application and select the End Task option. After that, try to open Windows Installer and complete the job you started to finish.

2. Look for Necessary Apps

Sometimes, you get Error 1603 if this program is already installed on your computer in an earlier version. Then, you first need to uninstall the previous version of the program.

Enter appwiz.cpl, click OK and you will be taken to the Control Panel for Programs and Features. Next, you need to select the program to uninstall and click Uninstall.

Confirm your actions and after completely uninstalling the program, try installing the required program again.

3. Examine the Disk

The hard disk may not have enough space to install the program. If this is the case, you first need to free up disk space by deleting unnecessary information, and then just install the program.

To check how much space is on your drive, click This PC and right-click drive C: Next, select Properties, you will be taken to the General tab, where you can see how much free space on your hard drive. Compare it with the program's requirements for the hard disk storage system and, if necessary, clean up the disk. The last step can be done using Disk Cleanup or other third-party software to remove temporary files.

After that, calmly launch Windows Installer and download the required applications.

4. Remove Temporary Files in the App
