Turn off UAC, or run the installation as Administrator.

Thanks for your reply.. i am totally stuck with this! i am installing from the administrator user, and the UAC is off ! but i still get the same error once the installation reaches 10%.

Mathworks provides free support for installation issues. (There might be some delay, though, as it is a holiday season.)

[Ashraf]

Thanks!

i cant believe it, this problem is making me crazy! how can I reach this support for installation?!

[Walter Roberson]

http://www.mathworks.com/support/install.html

and note the "contact support" link on the top right of that page.

I suggest you follow the kind of procedure described by satiu77 in http://answers.microsoft.com/en-us/windows/forum/windows_7-security/how-do-i-get-round-windows-7s-file-permissions/d048994f-7a95-469d-b2f5-b334b236a5e3 . You should be able to start at the B.dll file and move upwards from there until you find a place that hard-codes permissions instead of inheriting them from a higher level.

[Ashraf]

UAC is disabled !

what else I have to do?

[Walter Roberson]

Check the Security properties of the individual files and directories using the mechanisms described by satiu77 .

[Ashraf]

My dear,

I checked the security properties for satui77

but for matlab installation, during installation there are folders created and the error comes to me.

where should i make these modifications, on which folder? on the matlab folder or on windows folders or in program files ?

the problem for satiu77, is solving copying folders from one directory to another..

please explain for me

I tried to install the packeges one by one. But I have to install "Matlab 7.13" as minimum, which is the basic package... and it is giving the smae error!
