Hello

"Couldn't load module C:\Program Files\Wireshark\plugins\1.0.5\ccs.dll:

The Specified module could not be found."

is the error window I have if I do not include the manifest inside the
dll.

To include the manifest inside the dll :
mt.exe -manifest <dll_name>.dll.manifest -outputresource:<dll_name>.dll;2

Plugin works for me.
dissector with C++ inside,
production : wireshark 1.0.3, Vista, Visual C++ 2005 EE
works on :
- 1.0.5 standard installation (Vista and XP)
- 1.0.3 standard installation (XP)
- 1.0.3 own build installation (Vista and XP)
