Hi flyer
No.
There are 2 download options.
1 single large file or 9 multiple files.
The 9 multiple files all need to be put in to a new folder.
Check that the files downloaded have not been corrupted by checking the number of bytes in each file from the link below.

Single file download check.

After downloading LSH3-2015 restart your system.
To install the 9 files use the LSH3-EDITION-2015-STARTER-SPLIT.EXE and follow the screen instructions.
Like wise as above if you are installing from the 1 large file then extract from the zip file and use the LSH3-EDITION-2015-STARTER-FULL.EXE
SH3 must be a fresh install and not in the default Program x86 folder.
Make a new folder like SH3 so your install path will look like C:\SH3.
