PC-related Clarity problems (Windows & Antivirus)

Installation

Installation to program files: In Windows 7, the folder Program files is protected, however, Clarity needs user access to the data and system files. It is not recommended to install Clarity there.

User privileges settings:

Clarity users must have read/write access to the Clarity system and data files. The default C:\Clarty (C:\ClarityLite) directory inherits the Read Only status from C:\ on administered systems. It is recommended to Install Clarity for the User that will use Clarity under the "As Administrator" option. If not possible, contact your local administrator to change the settings.

Antivirus programs:

Antivirus programs usually do not interfere with Clarity functionality. But two areas may pose problems for the correct functioning of Clarity:

Antivirus is causing processor overload in certain situations, which may leave insufficient memory resources for Clarity.
Antivirus continuously monitors files frequently updated by Clarity (.raw, .audit, etc.), which may be unjustifiably marked as a threat to the PC.

Windows Updates:

Automatic Windows updates are in the default settings that force the unattended computer to restart regardless of running programs - only a warning message will appear. Please note that the first two options (Automatic updates or Download updates) may result in a forced computer restart.

We recommend installing and operating Clarity on a PC with updated OS, only the forced restarts pose a potential problem to Clarity.

In Windows 10 and 11, it is not possible to forbid the updates; just pause updates for a short period of time and install them manually to avoid forced restarts. Go to Settings - Windows Update - Advanced Options - Pause Updates

In Windows 7, 8.1 go to Control Panel - System and Security - Windows Update- Change settings.
Choose one of the options for automatic updates:

Never check for updates.
Check for updates, but let me choose whether to download or install them.

Ask your local administrator to choose one of the options described above on administered systems.

Control Modules and Tools

User Account Control (UAC) needs to be disabled during the installation of some control modules (CTC PAL, Shimadzu LC systems)

To install the CTC PAL autosampler or Shimadzu LC-10/20 system it is necessary to disable the UAC (User Account Control) during installation, otherwise, it will be unsuccessful. Similar problems were reported for the installation of the Agilent 1100 system, again the UAC disabling helped.
