I download Create Word Document Activity (Word 2007) solution from
code.msdn.microsoft.com/.../View.aspx%20samp\
les&version=16.

I am able to open solution successfully, but whenever I try to build the project
it is giving me following errors

Error 1 Source file 'C:\WINDOWS\TEMP \9nrls7rq.cs' could not be opened ('The
system cannot find the path specified. ')
Error 2 Metadata file 'C:\Documents and Settings\SPADMIN\My
Documents\activities\CreateWordDocument\bin\Debug\CreateWordDocument.dll' could
not be found. C:\Documents and Settings\SPADMIN\My
Documents\activities\TestCreateWordDoc

Actually I want to use this activity with a sharepoint list, whenver a list item
will create, I want to create a document with mail merging of list item
information and email it to assignee person.

Please advise me how do I resolve the issue and how can I use in sharepoint
designer?
