Welcome to SolidWorks forums Alex.
Please uninstall the older version completely and then install the newer version and check if you still get files missing error.

i checked to make sure it was completely unitalled but i keep getting the ame result. To walk you through what im doing.
1.) insert disk
2.) window opens with 'File currently on disc'.
- solidworkssetup64(zip file)
3.) I click on solidworkssetup64
4.) it suggests to unzip to D:\ but it does not work
5.) so i opt to unzip to the desktop
6.) it then says 280 files unzipped, then it opens solidworks installer manager
7.) Then it asks for type of installation. Individual, administrative image, server products, download only
8.) I choose individual
9.) it asks for serial number, but its already inputed
10.) I clicked next and it verifies the number and fails, i try again and then it works
11.) i get to a summary screen and i assume everything is how it's supposed to be, i check the drop down boxes and stuff is already selected so i click install now(4.6GB)
12.)A box pops up saying 'additional files are needed on the product selected'.
13.) it lists a whole bunch of toolbox files that are missing and edwrawings.
this is the point i pretty much get stuck on and don't know what to do.
when i click on the DVD files i supposedly unzip it doesn't seem to contain any thing but languages.
Any chance if you're trying to install SolidWorks Student Kit?? If yes than that is standard version with no toolbox.
Else if you can uncheck toolbox and edrawings where you select products to install and see if you can continue with the installation.
Yes, it is a student edition and i unchecked the toolbox and then almost all of the other options and it still asks for the toolbox and other files.
