Understanding the role of Ica-x64.msi leads to effective troubleshooting. The most straightforward solution to a missing Ica-x64.msi error is to re-download a fresh copy of the CorelDRAW 2020 installer from the official Corel website or to locate the original installation media. Users should never attempt to delete or manually move this file from its original subdirectory (typically found within a folder named x64 or ICA inside the main setup package). Doing so will break the software’s ability to receive updates or be properly uninstalled. Advanced solutions involve using Microsoft’s msiexec command-line tool to re-register or uninstall the specific component, but these steps are generally recommended only for system administrators.
To understand Ica-x64.msi , one must first appreciate the function of an MSI (Microsoft Installer) file. An MSI is a database package used by the Windows operating system to manage the installation, maintenance, and removal of software. When CorelDRAW 2020 is installed, it does not consist of a single executable; rather, it is a collection of dozens of interdependent MSI and support files. These files ensure that registry keys are correctly written, shortcuts are created, and, most critically, that prerequisite components—such as Visual C++ runtimes, .NET Framework updates, and proprietary Corel libraries—are present on the host system. Ica-x64.msi fits precisely into this latter category. Ica-x64.msi Corel 2020
The Enigmatic Component: Understanding Ica-x64.msi in CorelDRAW 2020 Understanding the role of Ica-x64
For most users, Ica-x64.msi operates silently in the background. However, it becomes visible and problematic when a setup routine fails. A common scenario encountered on technical forums involves an error message stating: "The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'Ica-x64.msi'." This error typically occurs when a user attempts to repair, modify, or uninstall CorelDRAW 2020, and the original source files (often an ISO image or a temporary extraction folder) are no longer accessible. In these cases, the system is looking for this specific MSI to reconfigure the shared ICA component. Users are then instructed to point the installer back to the original downloaded folder or re-mount the installation disc. Doing so will break the software’s ability to
The filename itself provides essential clues. The suffix x64 clearly indicates that this package is compiled for 64-bit versions of Windows, which has been the standard for modern systems since the late 2000s. The prefix Ica is more enigmatic but strongly suggests an internal Corel acronym or project name. Based on technical analysis and user reports from Corel’s support forums, "ICA" most likely refers to the Installation and Configuration Architecture or a similar internal framework used to manage shared components across Corel’s product line. This file is commonly associated with the deployment of Microsoft Visual C++ Redistributables or Windows Imaging Components —libraries that CorelDRAW 2020 relies upon for tasks such as rendering effects, managing color profiles, or importing/exporting specific file formats.

Note: the Vcc setting jumper only has effect when you are using AC adaptor as power source. For the USB power only 5V Vcc is available. For the PCB5.5C, set DIP steps: 1. press DIP Set button twice to check current DIP bit position. Then set it again for ON or OFF. 2. press DIP Bit shift button to shift the DIP bit position to where need to set. And then press DIP Set button twice to check current DIP bit position. Then set it again for ON or OFF. 3. Repeat those steps till all DIP bit ae set same as software indicated. For PCB5.5C voltage and Special chip selection: 1. Put back the safety jumper. 2. Press the voltage button and hold for 1 second, the voltage LED should move to next. Repeat till desired voltage LED light up. 3. Press the chip selection button and hold for 1 second, the chip LED should move to next. Repeat till desired LED light up. 4. Remove the safety jumper to lock the selected voltage and chip selection  DIP Switch (PCB3.5, PCB5.0)
