crash displaying MUI destination panel
This panel is not often displayed for us because it has to be the first product install for the panel to be displayed. I have a pre function that aborts the display if there are previous installed products which keys off a windows registry entry previously saved. During testing, some people have been crashing when this panel is suppose to be displayed. For me, I saw the crash just once and then never again. I did capture a bit of information on the crash:

That code is from a DLL and not from the installer itself. From the image base, I can say it's ntdll.dll, but not much more can be said without a script that reproduces this, the version of NSIS used and preferably a stack trace.

This problem was corrected by removing the LockedList plug-in from the install. I changed our installs to use a .oninit style rename and test of the destination product directory to determine locked files.

The old plug-in crashes on Win 2000 I have found, and this is due to the function GetProcessImageFileName only existing on Win XP.

Will have the new version ready soon.
