The original HI software was compatible with Microsoft's early Operating Systems, Windows 95 and 98, but over the years as they have modified and updated their software HI has adapted to remain compatible with the latest MS such as Win NT, 2000 or XP to run your Harrison InnerView IV4.05B applications on.
The combination of this Driver and IV4.05B will give you the most consistent results.
This will require you to install Harrison InnerView Version 4.05B and install the above driver together replacing previous system configurations. If you are setting up a new client and require a disc copy of IV4.05B just contact your HI administrator.
Remember to always back-up your HI files prior to upgrading software.
