Special Installation Note for Nihon Kohden 2100, 1100, and 9100 EEG

By default, AutoStart for Reveal and MagicMarker are off for compatibility with Persyst LightHouse. Selecting on from the Command drop-down will not save this setting in the Windows Registry. The result is that Reveal will not launch when the next recording stage is started.

To fix this, download and launch the following registry keys that will save the AutoStart setting for Reveal and MagicMarker.

IMPORTANT: These are for use with Nihon Kohen instruments running integrated Reveal and MagicMarker. Do not use this when launching these programs with Persyst LightHouse (otherwise the programs will crash).

AutoStart Registry Entries:

Reveal AutoStart On

Reveal AutoStart Off

MagicMarker AutoStart On

MagicMarker AutoStart Off


The directory \NFX includes old versions of system files named mfc42.dll and msvcrt.dll. The Persyst programs require new versions of these files, which are installed by 1999.06.23 (and later) to the \Windows\System folder.

Since NKReview is invoked from the NFX directory, the older versions of these files are loaded and the EEG Suite PlugIns (SpikeDetector, Prism, and MagicMarker) will not run. This problem will affect any software, e.g., Microsoft Word, if NKReview is launched first.

The fix is to simply delete these files from the \NFX directory as newer versions are stored in the Windows\System directory.

International customers: If you are using a version of Windows 95/98/NT other than the English Language version please check with your Nihon Kohden representative before performing this upgrade or deleting these files from your \NFX directory (as these files are language-dependant).
