BSOD ctclsflt.sys

[mckinnley]

i did an upgrade on my computer yesterday where i went from vista to windows 7 (64bit). so far everything has worked fine except for my camera, every time i try to use it in any program i get a BSOD with a stop error code of 0x0000007E
also it tells me that the problem is with some file called ctclsflt.sys
so after going through the registry and stuff i ended up finding that this file (obviously) is assosiated with my webcam. it's a creative IM ultra or something like that. i tried uninstalling and reinstalling the driver but it still won't work, i still get the same BSOD error and everything.

Did you download the latest drivers from Creative? They have them at http://support.creative.com/downloads/welcome.aspx?nDriverType=1#type_1

Apparently, they have the latest drivers for Windows 7. Try that.

yeah i downloaded and installed that driver, i still have the same issue. i know that the camera works and everything because i was able to use it on my laptop

well that's strange, for one reason or another that fixed my problem, i have no idea why that would do it since it's not a driver but hey, computers can be finicky sometimes. thank you so much for your help

It probably had more to do with the software interfacing with the camera than the driver. You were probably using an older version that was doing something illegal with the driver.

After 1/2 day of searching, debugging, etc., I uninstalled Creative Technologies Webcam Central, which apparently owns CTCLSFLT.sys. The problem went away, along with CTCLSFLT.

System: Vista Home
Problem description: After every sleep, BSOD, reason code "0000000A" (offset 749 in CTCLSFLT.sys).
