Follow the Performing Single- and Multiple-User Installations instructions, and choose an installation folder that is a hard drive on your local machine.

When installing QuoteWerks on a Windows 7 or higher machine, it's important to note that these operating systems do not allow programs installed in the C:\Program Files or C:\Program Files (x86) folder to save data anywhere inside that folder. QuoteWerks needs to save data in its own \QuoteWerks folder, so install QuoteWerks into a folder such as C:\Applications\QuoteWerks, DO NOT INSTALL QUOTEWERKS TO THE C:\Program Files or C:\Program Files (x86) folder.
