AutoCAD (am I allowed to say that here?) installs GD&T fonts. Look for fonts AMGTD and GTD.
This all works on my computer because I have a couple of ancient versions of AutoCAD on here from a previous life. I have no idea of how SolidWorks implements GD&T symbols. You might just want to search through your fonts, AutoCAD or no AutoCAD.
There's a font called SWGDT that I tracked down somewhere, free of charge. Unfortunately, it's free for a reason. It gives you the most of the basic symbols, but no datum symbols, no FCFs...not terribly useful.
If you're doing technical writing of any kind, SWGDT just won't cut it. After quite a search, I purchased PIXymbols for very little. You can compose complete FCFs to two-levels (composite). The datum callout symbol is missing. I tracked down the font creator and they are are working on a couple of corrections; the person whom advised him on the font set originally set him up with a mixture of 1982 & 1994 symbols per their preference. There are others out there as well, including some with the a more complete/accurate symbol set, but many of them are more expensive. I've used PIXymbols in MSWord & in Adobe Illustrator CS2 without much issue.
For the minor fee (around $30 as I recall), this is a great package.

Enter P22 GD&T into Google and you will find a link for myfonts.com. This fonts works with Microsoft Office.
I have used it in a number of reports in Word & PowerPoint.
Just remember to sent the font file to anyone you send a report to.
