it gives error 

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 bin folder 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.
