Microsoft’s August 12 updates for Windows 11 version 24H2 (KB5063878) and Windows 10 (KB5063709) have introduced an unexpected problem for schools and businesses. IT admins have discovered that the update forces secondary MSI installers to request administrator approval—something that previously wasn’t required.
The change is causing Error 1730 when standard users, such as students, cannot provide admin credentials after being hit with a UAC (User Account Control) prompt.
What Changed
MSI files are the backbone of many Windows app installations, from setup to updates. Normally, after an administrator performs the primary installation, a secondary MSI process may run the first time a new user account launches the software. This step handles things like licensing data, profile creation, and copying files to the user’s home directory.
For years, this per-user step worked without needing admin rights. But since the August update, these secondary installers now demand elevation—blocking students and standard users from completing the process.
“All software running a secondary MSI installer does this now,” one university IT admin told us. “Previously, it just copied app data for the user. Now it suddenly requires admin permissions, and if the student clicks ‘No,’ they hit Error 1730.”
Widespread Impact
The issue isn’t isolated to Autodesk apps like AutoCAD, Civil 3D, and Inventor, though those are among the most affected in academic labs. Any application that relies on a per-user MSI step can trigger the problem.
Logs shared with Windows Latest point to changes in msi.dll (updated from version 5.0.19041.5965 to 5.0.19041.6216 on Windows 10) as a possible cause.
Microsoft and Autodesk Respond
Microsoft has acknowledged the reports and says it is investigating. Autodesk has also confirmed awareness of the issue and is in contact with Microsoft. For now, Autodesk recommends rolling back or pausing Windows updates if organizations cannot adjust their policies.
This MSI bug is just the latest in a string of problems tied to the August 2025 Patch Tuesday release. Users have also reported SSD corruption issues, audio/video playback problems, and general instability since installing the updates.
Until Microsoft issues a fix, schools and businesses may be stuck either granting admin access to users who need secondary MSI installs—or holding back updates entirely.
