Error : Security ID may not be assigned

Hi,

I'm having some issues uncompressing a rar file, and I believe as something to do with windows 7 security.

I have Windows 7 Home Premium 64bit, and when I try to extract files from a rar file, I get the following messages:

! C:\backups\Documents.rar: Cannot set Documents\file.doc security data
This security ID may not be assigned as the owner of this object.
I'm getting really tired about this Windows 7 and all this crap security stuff.

The windows automatically logs me in with the account I created during the windows setup, and I'm the administrator of the machine.

How can I make this stop appearing?

Update:

I use the explorer shell to select "Extract to ..." that apparently just runs WinRAR with my user ... if I go to the WinRAR start menu and select "Run as administrator" it doesn't give me errors anymore, although I'm the administrator of this machine.

But how can I prevent this extra step? I'm used to execute the explorer shell extensions, and if the file system prevents for a clear way of doing it, it sucks.

Also still I'm getting this error, even running as administrator:

! C:\x\backups\Documents.rarr: Cannot set Documents security data
The security descriptor structure is invalid.

?!?!?!?!? Currupted? I believe I've tried in linux and had no problem at all ... 🙁


Thanks

That security "crap" is there for a reason and works just fine if you work with it instead of wasting time trying to get around it.

Have you checked to see if there's a version of WinRAR that's been updated for UAC?

WinRAR has been UAC compliant for couple of years... Odds are he didn't give his user the correct rights to the directory. Or if this is a backup from another computer the SID information is invalid. Extract it with out the security defs (honestly had no idea winrar could do that.)

I'm pretty sure WinRAR has supported storing ACLs and even ADSes for a while now, but no one really uses it.

I'm the administrator of this machine, i'm auto-logged with the user I indicated during install.

I've created this directory myself, so I'm the owner of it, the WinRAR it's the latest version, and the RAR file was copied to a USB pen, from my linux laptop.

How can I extract it without the security defs?

(I understand that security it there for a reason, but I'm new to Win7, and I'm struggling with it on this matter ... which gets frustrating sometimes 🙁)
 
I use winrar but never had it save security information. Quick google search says "update to the latest version of WinRAR." Beyond that I won't be much help with it since I have never used it that way.
 
I had this problem also. Turns out right click, properties, and in the general tab theres a button that says Unblock. Press that, click Ok. After that I extracted the files and the error message came up, but it worked anyway.
