hello, my name is Asaf and I recently installed ArcGis descktop 10, Every time I try to download a map package I get a message: invalid package> error reading package content. I'd be gratefull to hear from anyone how might know how to solve this problem

here are the steps I took to download and install the program:

ArcGIS for Desktop Student Trial software Instructions

A. Before you install ArcGIS for Desktop   

1. Check Esri’s system requirements to make sure your computer has the hardware and software required for the trial.
2. If necessary, uninstall previous versions of ArcGIS Desktop or Server.  The software cannot be installed on a computer that has a previous version of ArcGIS Desktop or ArcGIS Server installed. It's OK if the computer has ArcGIS Explorer installed.
3. If necessary, install the Microsoft .NET Framework (version 3.5 Service Pack 1 or higher).

B. Activate your authorization code 

1. Visit www.esri.com/educationedition to begin the process of activating and downloading your ArcGIS for Desktop Student Trial software.
2. Log in using your Existing Esri Global Account, or Sign-up for a new Esri Global account, if necessary.
3. Enter the authorization code EVAxxxxxxxx9 and click Activate ArcGIS.
4. Click ArcGIS 10.0 for Desktop.

C. Download and install ArcGIS for Desktop Student Trial

1. If you would like the software in a language other than English, select your preferred language.
2. Click the link “a. Download ArcGIS Desktop 10.”  You can also download the Tutorial data, if desired.
3. If you are installing from an ISO image, locate and unzip the ArcGIS for Desktop ISO using 7-Zip.
4. Locate and Run Setup.exe to install ArcGIS for Desktop. The “Complete” installation is recommended.
5. After the files are installed, the Authorization Wizard will open and prompt you to choose a product to authorize; select “ArcGIS Desktop – ArcInfo (Single Use)” and click continue.
6. The Authorization Wizard will prompt you for an authorization code; enter your activated code.  Follow the prompts and the software will authorize and be ready for use.  Note: leave the default option for the software extensions selected; they will be authorized automatically

Thanks Asaf

I had this problem in my previous laptop which didn't have enough storage

space so the arc was installed in an external hard drive. I thought maybe

that was causing the problem. So I installed arc in a new laptop (local

drive) wich meets the requirements for arc, according to the system

requirements checkup. Maybe I'll try reinsatalling version 10.3 if I can,

as its a students trail authorization.

Thanks anyway, Dan and everyone who responded to my post.
