If you have arrived on this page, you are looking for the original (OEM) drivers for your Endoscope camera.
Perhaps you lost the miniCD that came with the camera, maybe the CD would not load on your PC, or your PC crashes when the camera is selected.
While searching for the driver, you likely found a series of websites that claim to have the driver, but require you to download and install a "Driver Updater" or "Driver Informer" or "Drivers for Free" software that watches what happens in your system, or "Install IQ" that supposedly "helps" you to download something the site may or may not have. These softwares all claim to locate the drivers present in your system, send this information out to some site (most commonly in China), and claim to inform you when the site has a newer driver version available for download.
Let's be absolutely clear on what this entails! To get all the driver details from your PC, you are being asked to allow a piece of software of unknown origin COMPLETE, on-going and uncontrolled Adminstrator-level read and write access to your system directories and into the entire Registry. The problem is of course that you have no idea what else from your PC is being sent.
Some driver update sites claim free downloads, but then ask for credit card and bank information ( bank information? Really? ) to pay for the "helper" application. Most, perhaps all, of these sites have numerous and large download buttons for products (often of limited utility or just plain useless) you are not looking for. Some of them have no way to just get the driver without all the unwanted trash.
These sites intentionally use what are called Dark Patterns. See darkpatterns.org for a discussion of these dirty tricks and how to spot them.

The BAD_POOL_HEADER problem
We ran into this when we tried to load the GUCI_AVS.SYS driver on an HP Pavilion laptop (AMD Athon K2 64 cpu) running Windows 7-32 bit. The 32 bit driver appeared to load correctly, Windows reported that it was working correctly, but as soon as the camera was selected Windows crashed. The driver worked perfectly on Intel based Windows 7-32 and -64 bit systems.
The cause appeared to be a subtle interaction between the 32 bit GUCI_AVI.SYS driver and how the Athon 64 bit cpu runs in 32 bit mode. The HP Pavilion was originally shipped with Vista-64, so we reinstalled Windows 7-64. The AMD64 OEM driver version of GUCI_AVS.SYS loaded correctly and the camera was initially fully functional.
After some additional testing, the BAD_POOL_HEADER crash reoccurred, and we eventually tracked down the real cause.
The GUCI_AVS installer includes and requires a second driver, PAUVCFLT.SYS for both 32 and 64 bit versions of Windows. If this second driver is not installed, selecting the camera causes the crash.
If you have tried to install the driver multiple times, some manual intervention is required to fully clean up Windows before you try the install again.
If this still does not work, please contact us here.
