AutoCAD 2016 User Account Control Error

[jitendra_guptaENA7X]

Hi, 

  

We are currently using AutoCAD Mechanical 2016 and since we don’t have AMC support, we are unable to upgrade. Recently, users started encountering a UAC prompt every time they try to open AutoCAD Mechanical. The application works only when admin permission is granted, but it does not run normally without it.

Here’s what I have tried so far:

• Reinstalled the application (issue still persists)

• Verified that Windows Defender is not blocking it

• Searched online but couldn’t find any relevant fixes

I am attaching the screenshot of the UAC error for reference.

Has anyone faced this issue before? Would appreciate any expert advice or workaround to resolve it.

Thanks in advance!

Hi, this is a known problem caused by the latest Windows updates. See the article https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/After-installation...
