Special considerations for Windows 7
Slow response from the screen keyboard and SmartServer
The following programs may start and respond very slowly under Windows 7 and Windows
2008 servers:
● Microsoft OSK screen keyboard and HMI TouchInputPC
● SmartServer: <Ctrl+Alt+Del> shortcut in the logon dialog
The delay is caused by the callback for the Internet certificate validation.
Remedy:
Locate the following files on the product DVD under:
Support\Windows7\CRL_Check or CD_RT\ Support\Windows7\CRL_Check\
:
● DisableCRLCheck_LocalSystem.cmd
● DisableCRLCheck_CurrentUser.cmd
1. Run the "DisableCRLCheck_LocalSystem.cmd" file with administrator rights. Select the
command "Run as administrator" from the shortcut menu of the file.
2. Reboot the PC.
If the problem persists, follow these steps:
1. Double-click the file and run the "DisableCRLCheck_CurrentUser.cmd" file with user
rights.
2. Reboot the PC.
NOTICE
The callback for the certificate validation is disabled for all users or PCs. To restore the
original state, perform the following files:
• RestoreDefaults_LocalSystem.cmd
• RestoreDefaults_CurrentUser.cmd
You can find the files in the following directory of product DVD:
• Support\Windows7\CRL_Check bzw. CD_RT\Support\Windows7\CRL_Check\
