I encountered this access violation error in Windows Vista SP1 RC while viewing a pdf file. Not sure whether it is due to Explorer View or SP1. But, prior to installation of Explorer View, I have been running SP1 without any issue.
After this error, event log is unable to run, wifi is not working and some of Kaspersky's components fail to run. Even uninstalling Explorer View does not resolve the problems. In the end, I have to re-install Windows Vista. This is definitely not a good start to a new year and this software is not recommended.
