I'm using the excellent NHunspell spell checking API in a click-once C# Win Forms application. (Word automation is a broken mess.) NHunspell is a wrapper around the Hunspell spellchecking library used by Open Office. It first determines whether to load a 32-bit or 64-bit library based on the machine. It assumes that all the files are in the AppDomain.CurrentDomain.BaseDirectory (and they are being properly installed to the same location.) For one user (and that user only) the LoadLibrary() API fails when it attempts to load the proper library file. It works for me and several others but always fails for that one machine. Does anyone know of other instances of LoadLibrary() failing from one of the crazily named click-once installation directories? Could the path be too complex? Any ideas appreciated except telling me to abandon click-once!

Hi CCPoston,

As far as I know, the path can cause the error if it contains some special characters. For example, if the path contains a period(.), the call of LoadLibrary would fail. You can get the details from: http://support.microsoft.com/kb/324468.

Could you please provide more information about the differences between the machines on which the program can be installed successfully and the machines on which the installation would fail? This can help us to restrict the error to a small area.

Best regards,
Aland Li
