Checking Integrity and Prerequisites

Check Integrity and Prerequisites On Windows

This tasks explains how to check integrity and prerequisites on Windows.

Select the Start > All Programs > MyProduct > Tools > Software Management V6R2012 command or run the program:
```
install_root\code\bin\CATSoftwareMgt.exe
```
where "install_root" is the name of your installation folder which is, by default:
```
C:\Program Files\Dassault Systemes\B211\intel_a
C:\Program Files\Dassault Systemes\B211\win_b64
```
The Dassault Systemes Software Management dialog box is displayed, and the General tab is open.
Click the Check Integrity tab:

Click the Check button to check the overall integrity of your software.

There are three integrity check levels:
- Level 1: only control files are checked; quickest
- Level 2: checks existence of all installed files
- Level 3: checks existence and validity of all installed files; may take several minutes.
The message:

Integrity is OK

confirms there is no integrity problem. However, when the message:

Integrity is KO

appears, your installation has been corrupted (for example, some files are missing), it will be followed by troubleshooting information helping you to identify the problem.

When running a level 3 integrity check on a remote computer from a Windows client, a read error may occur on several files due to a saturation problem.

These errors may cause the following message to appear:
```
unable to open this file in reading mode
```
The problem may be resolved by deactivating the cache of the network redirector on the client computer, by modifying the following registry key as follows:

1. Open the registry at the following location:
```
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Lanmanworkstation\parameters
```
2. Modify the following value:
```
Value name: UtilizeNTCaching
```
```
Data type: REG_DWORD
```
```
Data: 0
```
Please exercise extreme caution when editing the registry. It is only recommended for advanced users with the proper authorization: deactivating the network cache may cause the computer's performance on the local network to deteriorate.
Click the Check Prerequisites tab.
This simply checks if you still have the prerequisite environment required for your product line to operate:

Clicking the Certified Configurations button opens the Hardware Certification section of the
