I just switched from XP to Windows 7 64 bit, and discovered that my usual method of opening uninstalled fonts to use in Inkscape doesn’t work with Win7. When I tried to install The Font Thing I got an error message and it wouldn’t install. What is a font addict to do? I found this solution and it works! Go to The Font Thing website here and then click on the Download tab. Download the second link on the download page. You want the one without the installer since you aren’t going to install the program. Once you have the files downloaded, unzip them, then for ease of use I pinned the TFT.exe to the taskbar. Just click on the pinned file to run the program.
When you click on the Browse tab, you might just get a question mark. If you click on the refresh button it will change to your C drive and you can navigate to where you have your uninstalled fonts stored. Then you can preview or temporarily load your uninstalled fonts. If you want to use TFT to install fonts, you will have to set it to run as an administrator before you open the program.
