Preparing the Windows 7 Workstation

Before installing McIDAS-X for Win7, verify that the workstation is configured to the specifications listed on the previous page. Then complete the four tasks below.

Preparing to Install SUA Using the Windows Interface

Complete the instructions below to create a new menu item enabling you to download the SUA installation package. For more information about SUA, see the Microsoft SUA Overview.

1. Log on to the workstation as Administrator. (Note that you cannot complete the instructions below as another user with escalated privileges; you must be logged on as Administrator.)

2. Click Start, and then click Control Panel to bring up the Control Panel window.

3. In the Control Panel window, click Programs and under Programs and Features click Turn Windows features on or off.

4. If the User Account Control dialog box opens, click Continue. Otherwise, proceed to the next step.

5. In the Windows Features dialog box, select the Subsystem for UNIX-based Applications check box, then click OK.

Installing SUA Using the Windows Interface

Complete the instructions below to install the SUA package.

1. Log on to the workstation as Administrator. (Note that you cannot complete the instructions below as another user with escalated privileges; you must be logged on as Administrator.)

2. Click Start and then, in the in the Subsystem for UNIX-Based Applications program folder, select Download Utilities for Subsystem for UNIX-Based Applications to open a webpage with link to download the SUA package.

3. Download the appropriate SUA installation file for your workstation configuration (e.g., 64bit x86, 32bit x86, 64bit Itanium).

4. Double-click the downloaded file to run the installation wizard.

5. After completing the customer information and license agreement, select Custom Install for the Installation Type and choose to install all features on the local drive.

6. In the Security Settings accept the defaults of none selected, and in the Installation Location, accept the default of C:\Windows\SUA.

Installing the SUA Community Complete Toolset

Complete the instructions below to download and install the SUA Community Complete Toolset.

1. Log on to the workstation as Administrator. (Note that you cannot complete the instructions below as another user with escalated privileges; you must be logged on as Administrator.)

2. Download the 32 bit version of the Complete Toolset from the SUA Community webpage. (Note: You must download and install the 32 bit [not 64 bit] version, regardless of your workstation configuration.)

3. Open an SUA Korn Shell and change to the folder where you downloaded the package in step 2 above. For example, if you downloaded it to the Downloads folder,

Type: cd  Downloads

4. Run the installation file. For example, if the file is named pkg-current-bundlecomplete60.exe,

Type:  ./pkg-current-bundlecomplete60.exe

The command above starts the SUA Community Complete Toolset installation. This process uses the pkg tools to install many common UNIX utility programs, and will attempt to contact various websites to auto-download updates. A connection to the Internet is recommended. Many packages will print warnings about the case sensitivity of the filesystem, but these can be safely ignored. The final step runs a GUI installer for XMing, an X Server that many people at SSEC use with McIDAS-X for Win7.

Disabling Physical Address Extension (PAE)

McIDAS-X may not run correctly or at all on 32 bit Windows 7 systems if Physical Address Extension (PAE) is enabled. This problem, which applies only to 32 bit (not 64 bit) Windows, can occur if OptIn configuration is set. The OptIn configuration enables Data Execution Prevention (DEP), which implicitly enables PAE.

You can check if PAE is enabled on your 32 bit Windows 7 system with Start > Control Panel > System and Security > System. If PAE is enabled, the bottom of the System section will include a line saying "Physical Address Extension". If it's enabled you should disable it and DEP by running the following commands in a DOS Command Prompt while logged on as Administrator (not another user with escalated privileges).

Type: bcdedit  /set  nx  AlwaysOff

Type: bcdedit  /set  pae  ForceDisable

For more information about PAE and DEP, see http://msdn.microsoft.com/en-us/library/windows/desktop/aa366796%28v=vs.85%29.aspx.
