I have installed Windows 98 in VirtualBox and the graphics are ****-poor, 640 x 480 16 colours. I have read on the internet to install Display Doctor 7 beta. It will not install. It comes up with, "An I/O error occurred while installing a file. This is normally caused by bad installation media or a corrupt installation file." I click retry and it comes up again. If I click abort, it exits the installation with this message, "Corrupt installation file!" Please don't tell me to install VirtualBox Addons, I have already told that and have found out that Windows 98 does not support them.
I tried installing Display Doctor 6.53, it installed but it wouldn't alter the graphics. I've been working on this for a few nights now, with little progress. Help!!
