Check that a method with the specified name and arguments exists and that it is static.

That looks a great deal like the library files have not been updated cleanly.  

Is edit-webapp empty of any jar files (C:\Program Files (x86)\Shibboleth\IdP\edit-webapp\WEB-INF\lib)?

Also, what are the file names inside 
	C:\Program Files (x86)\Shibboleth\IdP\dist\webapp\WEB-INF\lib\idp*.jar

(they should have the tag 3.4.3.jar *NOT* 3.4.1)

And can you confirm that there is no file called

	C:\Program Files (x86)\Shibboleth\IdP\ webapp
