A recent update to Windows is causing a major problem for students and schools. After installing the update, many people find they can no longer open important programs. Instead, they see a message that says “Error 1730.” This issue is creating a significant headache in places like universities and schools where many people share the same computers.
This trouble started after Microsoft sent out its security updates around August 12, 2025. The specific updates causing the problem are KB5063878 for Windows 11 (version 24H2) and KB5063709 for Windows 10. It seems a change was made in how Windows handles certain types of program files, which has led to this widespread issue.

The Problem: A Sudden Demand for Admin Rights
The heart of the problem lies with a special type of installer file known as an MSI file. Think of a program on your computer like a big model playset. When the main software is installed by an IT administrator, it’s like building the main structure of the model. This is the primary installation. It sets up the core parts of the program that everyone will use.
However, many complex programs, especially ones used in schools like AutoCAD, need to create a special, personalized space for each user. When a student logs into the computer for the first time and tries to open the program, a secondary installer runs. This installer’s job is to set up things just for that student. It might lay down licensing information, create a personal user profile, or copy specific settings to the student’s folder. This happens a lot in school computer labs, where new students are logging in all the time.
Before the August 2025 update, this secondary step happened automatically in the background. It didn’t need any special permissions. But after the update, something changed. Now, when this secondary installer tries to run, Windows stops it. A box, called the User Account Control (UAC) prompt, pops up on the screen. It asks for an administrator’s password to continue.
This is where the real trouble begins. In a school, students use “standard” accounts. They do not have administrator passwords. So, when the permission box appears, their only choice is to click “No.” When they click “No,” the process fails, and the system shows “Error 1730.” This error simply means the program couldn’t do what it needed to because it was denied the required permission.
Who Is Affected by This Glitch?
This issue is not just a small inconvenience; it is preventing students from accessing software they need for their classes. An IT administrator at a European university explained the situation, saying, “We have several applications behaving this way, not just those from Autodesk.” This means that any software that relies on this secondary installer process is affected.
Some of the key programs reported to have this problem include:
- AutoCAD
- Civil 3D
- Inventor (versions 2022–2026)
These applications are very common in engineering, architecture, and design courses. The problem appears to be widespread, affecting both Windows 10 and Windows 11 machines. One IT technician for a large university environment spent a whole day investigating the bug and concluded, “This Autocad Issue looks way bigger than just AutoCAD.” The issue stems from a fundamental change in a Windows file called msi.dll, which is responsible for handling these installations.
What Should You Do About This Error?
The good news is that both Microsoft, the creator of Windows, and Autodesk, the maker of AutoCAD, are aware of the problem. They are reportedly in communication to find a permanent solution. However, a fix from Microsoft in the form of a new update may take some time. Until then, there are a few things that IT administrators in affected schools and organizations can do.
Temporary Solutions for IT Administrators:
- Pause Windows Updates: The most direct way to avoid the problem is to prevent the troublesome updates from being installed in the first place. You can pause automatic updates in your Windows settings.
- Uninstall the Update: If the update has already been installed, you can uninstall it. For Windows 11 24H2, this would be KB5063878. For Windows 10, it is KB5063709. This is the official recommendation from Autodesk for those who are severely impacted.
- Wait for a Patch: Since Microsoft is aware of the issue, a patch to fix the bug is expected. If the issue is manageable, waiting for the official fix is the safest option.
It is important to understand that uninstalling a security update can leave your systems vulnerable. These updates often contain important fixes for security holes. Therefore, you should weigh the risk of not being able to use certain software against the risk of being exposed to security threats.
For students who encounter this error, the best course of action is to report it to their school’s IT department. They are the only ones with the ability to apply these temporary fixes.
A Troubling Trend for Windows Updates
This installer bug is not the only issue people have reported with the August 2025 updates. Some users have also mentioned problems with their computers’ performance, including issues with solid-state drives (SSDs) and difficulties with audio and video streaming. These combined problems paint a picture of a difficult month for Windows users and IT professionals.
When operating system updates cause such significant disruptions, it creates a challenging situation for organizations that rely on the software to function. For schools and universities, where access to educational tools is critical, the impact is particularly severe. It disrupts learning and adds a heavy burden to already busy IT departments. The focus now shifts to Microsoft to deliver a reliable fix that can restore normal operations for everyone affected.
