The DLL is written in C, so I can't get useful stack trace information out of it with MadExcept, and the problem is not reproducible on my end. And just to make things worse, I don't even know what EPrivilege is. I've never seen it come up in my own code, there's very little information about it available online, and what there is is contradictory. (One explanation says it's raised by the OS if you try to do something with a limited account that requires privileges that aren't available, another says that it's raised by the CPU if you try to execute an instruction that's above your privilege level.) Does anyone have an authoritative explanation for what causes EPrivilege? And does anyone have any idea how it could be raised by music-playing code on one Windows 7 64-bit machine under a non-admin account but not be raised when running the same code on my Windows 7 64-bit machine under a non-admin account? delphi exception sdl delphi-xe privilege share|improve this question asked Jun 24 '11 at 22:10 Mason Wheeler 58.4k29186342 The RTL source doesn't really give any clues... –Andreas Rejbrand Ju

I would assume you trashed a return address on the stack and transferred control to someplace you shouldn't have. Jerem Delphi Developer Thu, 29 Jul 2010 01:02:57 GMT Re:What causes Exception: "Privileged instruction" Ok, that sounds like a special case of an access violation.

Windows Errors

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.

Blue Screen of Death

A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".

Damaged DLLs

One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.

Freezing Computer

Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.

Virus Damage

Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
