Installation

Lexicon Studio Installation Troubleshooting

If after installing Lexicon Studio drivers and restarting your computer your computer boots with the
message: 'Core32 or Core2 not installed' or 'not working properly', go to
http://www.lexicon.com/downloads/studio_download.htm and download Core2 PC V1.20 Patch:
C2V120P3.exe.

If, when attempting to launch the Lexicon Control Panel for Core2, it flashes for a second and then
minimizes, go to http://www.lexicon.com/downloads/studio_download.htm#Core2SP2 and download the file
C2V120P2.reg. Double click on the file, let it run, then restart your computer.

1. Make sure Lexicon is not sharing an IRQ with anything other than IRQ Holder for PCI Steering. If it is,

try moving the Lexicon card to another PCI slot. To check for IRQ sharing, go to the Start menu and
select Settings, Control Panel. Double click to open the System control panel. Go to the Device
Manager and double click on Computer. Look for Lexicon IDS Sound System in the list of devices. Take
note of what IRQ it is on. Check to see if there is anything else using that IRQ (it is okay for it to share
with IRQ Holder for PCI Steering). If Lexicon IDS Sound System is sharing an IRQ, try moving the card
to another PCI slot. Then check the IRQ again. If you are unable to get Lexicon onto its own IRQ, give
Lexicon Tech Support a call at 781-280-0300 or email:

[email protected]

2. Go to the Start Menu. Select settings, Control Panel. Double-click on MultiMedia. Go to the devices tab

[Advanced if using Windows 95]. Look under audio devices. Double-click on Audio for Lexicon Studio
Wave Device. Check the status. It should say drivers enabled and active. If it does not, restart the
computer. Note - Check again and restart again if not enabled.

3. If you are experiencing pops, clicks, or random crashes, try turning the video acceleration on the

graphics card down to none.

4. Turn Read Ahead optimization to None in the Windows(r) File system properties control panel.
5. From the Troubleshooting tab in the Windows(r) File System properties select Disable write-behind

caching for all drives (put a check mark beside it).

6.  Use a separate drive or partition for audio. Defragment all hard drives regularly.
7.  Run scandisk.exe or other disk utility regularly.
8.  Disable screen savers, background applications that aren't needed for audio, disable virus protection

software while using an audio application (re-enable it whenever you are downloading files from the
internet, receiving email, or inserting disks into your machine).
