For Modbus you are probably missing this library: http://www.ni.com/example/29756/en/

The ADO vi is from a database toolkit. Probably NI's database connectivity toolkit.

Already installed this library even though this error might occur. Is there any alternate solution to solve the problem?

If you are sure it's installed (and where), LabVIEW might look for the files in the wrong place. When lv searches for the vi's, press the browse button and navigate to the vi manually. You might need to repeat this a few times. When all files are located, and the project is saved, next time you should not have to do it again.
Another option might be that the original programmer made these vi's and store them in the libraries. That means they are simply lost... It's unlikely though, most of us don't bother making polymorphic vi's for one time use.

About Modbus. You should download this library http://www.ni.com/example/29756/en/ (download link http://ftp.ni.com/pub/devzone/epd/nimodbus121.zip)
It contains a "NI Modbus.llb" library that contains poly VI 'MB Serial Master Query (Poly).vi' and others.
