I don't know what I do to my computer, but the point is that it can't execute some programs like:

iTunes
Macromedia Dreamweaver
Macromedia Fireworks
Macromedia Flash
Microsoft AntiSpyware
MSN Messenger
and others...

It says I didn't have acces to this program

Is there any cause or solution to this?

Thanks

I can't read it cause it's in some language... but are you an administrator? (killed that with spelling )

Well, yes I'm an administrator and maybe you didn't understand the language becuz I am Mexican.

But I can't install programs that are installed with Windows Installer becuz it says I don't have the priviligies to modify some file that install (for example in messsenger is says that I don't have the priviligies to modify the file "license.trf" and then it uninstall the program).

I don't know what i did becuz it can't install these programs.

do u have IE7 installed?

No, I have download the program file but I haven't installed it becuz it think it will be the same error that the other programs.

But why that question?

Try right-clicking on the ".exe" file and chose run as > Adminsitrator and give the Administrator password. If this doesnt work then maybe ull have to format your computer .

It doesn't seems to work, well I will format my computer

Thanks

did you lock the files? Cause by the look of it, it shows locked as the name of locked files is in green or perhaps you have tweak it to change the compressed color to green?

And locked files cannot be accessed. Only unlocking it will help.

Yeah, the name is in green, but how does it works?
or is there any solution?(except formatting).

Thanks for reply

Right click on any files, clcik properties > advanced. Check whether the box next to encrypt contents is checked. If it is, unchecked it, enter the pass, this will unlock the file and you can gain access to it.
Edit: If you forgot the pass or you are not the one who locked it, find the person and ask for the password to unlock.

I have my program files and my Windows Live Messenger folder encrypted what folder I disencrypt?

any folder that you've encrypted? Like Windows or System 32 folders? Or your whole hard disk? disencrypt the whole harddisk is the best. Only encrypt your documents or files. don't encrypt any program files, otherwise it will be difficult to access any programs installed.

It don't remember if I encrypted it, but the only folder encrypted is the program file, I'm desencrypting it and all the subfolders, thanks for the info.
