server error in '/owc' application. not load file or assembly 'owc' or 1 of dependencies. attempt made load program incorrect format.
the error message means file owc.dll or 1 of it's references missing.
check whether file either:
- in
binfolder of web project (after publishing); - in gac (c:\windows\assembly).
if exist there, can use reflector, or similar products see references of owc.dll , have check references too.
