3-1. I can’t activate the installation due to the error “Could not initialize installation. File size expected = 1416160, size returned = 229376."  Top

Because your download is interrupted due to a network problem, the file size is not enough for installation to be activated. So please try again to download the setup file. During the download, remember to close all other running applications (even instant messengers) to optimize the process and avoid download interruption.

3-2. I want to uninstall the program, but an error comes up saying "Could not open INSTALL.LOG file. What should I do?  Top

This error is a rare case. If it does happen, please try doing as follows to uninstall the program: 

- Go to the installation folder of the program (often in C:\Program Files\...) and delete this whole folder. Then open the Recycle Bin and remove it one more time from your computer. 

- Click the Start menu > Run > type "regedit" > the Registry Editor window comes up > HKEY_LOCAL_MACHINE > SOFTWARE > Avnex > delete this folder.
