DreamCatcher no longer lists this game at their site: http://www.dreamcatchergames.com/dci/pc.php
. So there are no patches available in the support site.
Curse: The Eye of Isis was issued for XP and older versions of Windows. The installers and drivers are totally different with Windows 7. What version of Windows 7 Home Premium do you have? If you have the 32-bit version, the compatibility mode might work. (It is less likely to work with 64-bit Windows 7. However, there are no guarantees for either version.)
To try using the compatibility mode: right click on the installer. Then choose Properties and then the Compatibility tab. Turn on Run program as Compatible with the appropriate OS. Then right click again on the installer and choose Run as Administrator. Make sure the program is running in the compatibility mode if it does install by doing the right click and Properties step again.
A method that will work but will cost more money is to use a computer (virtual, dual-boot, or true second machine) with an older version of Windows installed. If you buy an upgrade to Win7 Pro or Ultimate, you can create a virtual XP computer for free. Download and install Virtual PC and XP mode from Microsoft. Install them in order. Then install the software from your CD in the virtual computer and it will work. (Other virtual computer programs are Parallels and VMWare.) All of the other options will require a licensed version of the older Windows OS.
I hope this helps.
