How Do I...
Following are some frequently asked questions about installation of IC-CAP programs on the PC.
Check the Nodelock ID of My Hardware Key
You need the nodelock ID of your hardware security key to get codewords from Agilent EEsof. It might also be useful to access this information when you place a call to Technical Support. There are two ways to check this:
| • |
Before you install the hardware key on your PC, you can read the id directly from the key. |
| • |
If you have installed the hardware key on your PC, and have also already installed your codewords and the FLEXnet software, enter a command to check the nodelock id: |
-
lmutil lmhostid -flexid
Delete All Installed Files
You don't have to uninstall all files before you run the Setup installation again. Any new installation supersedes previous installations. However, the Uninstaller is useful whenever you want to make sure you have deleted all installed IC-CAP files, including registry entries.
To run the Uninstaller program:
| 1 |
Close all IC-CAP applications. |
| 2 |
Select Start > Programs > IC-CAP 2008 PC > Uninstall IC-CAP 2008 PC. |
| 3 |
Answer yes to the prompt that asks whether you want to remove all IC-CAP applications and components. |
| 4 |
When the uninstall process is complete, a prompt will indicate when the uninstall process is complete. Click OK to dismiss the dialog box. |
|
Note
|
|
|
|
|
Be sure you have exited all applications before running the Uninstaller program. If you have not, it is possible you will get errors upon re-installing IC-CAP. If these errors occur, reboot your computer and start the new installation again, or search for and end the lingering application(s) through the Windows Task Manager and start the new installation again.

Change the Home Directory
You can change the IC-CAP home directory by setting an environment variable named HOME or by changing the value listed in the registry for your IC-CAP home directory. If you set an environment variable named HOME, then IC-CAP uses that before the value listed in the registry.
To change the value listed in the registry for your IC-CAP home directory:
- Type regedt32.exe
- Click OK.
| 2 |
Inside the registry editor, find the folder or window titled HKEY_LOCAL_MACHINE on Local Machine. Select Software > Agilent > IC-CAP > 6.2 > eeenv. You will see a registry entry called |
- HOME: C:\users\default.
- (This is only true if you accepted the default startup folder during installation.)
| 3 |
Double-click this entry to open the string editor. Change this to reflect the path of your new home directory. |
| 4 |
Change the Start directory of the IC-CAP Main window's file browser. Select the following: |
- Start > Settings > Taskbar & Start Menu Programs > Advanced > Advanced.
- This opens the Explorer window.
| 5 |
On the right side of the Explorer window, double-click the Programs icon. |
| 6 |
Open the IC-CAP 2008 PC icon. This displays the shortcuts to IC-CAP executable. |
| 7 |
Right-click the IC-CAP icon and choose Properties |
| 8 |
Choose the Shortcut tab. |
| 9 |
Change the field Start in: to reflect the path of your new home directory. |
Ensure Hard Disk Storage Efficiency
This section provides an overview of the effects different types of file systems and different partition sizes have on the disk space required for installation of your IC-CAP application.
See the table below for definitions of some important storage terminology.
Table 2 Storage Terminology
sector
|
The smallest unit of disk space that the hardware can read or write to, and it equals 512 bytes.
|
cluster
|
A group of one or more contiguous sectors and is the smallest unit that a file system can allocate (hence it is also referred to as an allocation unit). For partitions larger than 16 MB, there are normally 4, 8, 16, 32, or 64 sectors per cluster. The number of sectors per cluster is determined when the hard disk is formatted.
|
file system
|
The means used by an operating system to store and retrieve files from a hard disk.
|
partition
|
A logical hard disk and appears on a PC as having a unique drive letter such as C:\. A physical hard disk can be divided into one or more partitions.
|
An IC-CAP installation typically contains thousands of files. Although many of these files are only a few kilobytes in size, they can occupy a lot more disk space than their individual sizes suggest. For instance, it is not uncommon for a 1 kilobyte file to occupy 32 kilobytes of space.
The amount of space occupied will depend on the type of file system that IC-CAP is installed on and the size of that particular disk partition. Identical installations can differ in space requirements by as much as 300% between different file systems.
Adding a new hard disk is a relatively inexpensive and common way to compensate for poor hard disk storage efficiency. However there are other options that can provide additional space without adding hardware. Options include changing disk partition sizes, changing file system types, and using disk compression software.
