Bad news for Windows 10 and 11 users. Following the August 2025 security patch, some applications are refusing to install. This notably includes Office Professional Plus 2010, which shows error 1730 during setup.
Unlike the false alert that affected SSDs, this issue is quite real. Microsoft has even confirmed its existence on its Windows Health Dashboard. Certain non-administrative users are unable to install applications. This is due to the KB5063818 update, which addresses a long-standing vulnerability in Windows Installer, referenced as CVE-2025-50173.
Windows blocks installation of certain applications after the August 2025 update
Among other consequences, there is an inability to run MSI repair commands such as msiexec /f. Users are also unable to launch certain Autodesk applications, as well as those that require user configuration.
There is a simple temporary workaround for this Windows bug: run applications as an administrator. If this is not feasible, environment administrators can propose a repair using the Known Issues Rollback.
As previously mentioned, the August 2025 security update has also been accused of causing SSD-related issues. Ultimately, Microsoft and Phison denied such claims. Windows 10, whose support end date is set to be extended by a year under certain conditions, is not spared. This bug affects both versions of the operating system, which means millions of users are impacted, especially in enterprise environments where non-administrative accounts are the norm.
We now must await a fix from Microsoft. In the meantime, the Redmond company provides comprehensive documentation regarding the bug on its official Windows Health Dashboard. Administrators can monitor the progress and the potential fix date.
This bug serves as a reminder that an operating system is never perfect, and even a patch can lead to significant issues. Microsoft is gradually improving Windows 11, which now offers version 25H2. However, these minor problems tarnish the user experience, and the company is doing everything it can to resolve them.
In short, if you are affected, the workaround remains to run applications in administrator mode. The good news is that it’s very simple to do:
- Right-click on the application
- Then, left-click on “Show more options”
- Next, select “Run as administrator”
