Troubleshooting

Can't register EquatIO

  1. Make sure you have access to EquatIO through Virginia Tech. Virginia Tech affiliates - faculty, staff, students, and alum - can use EquatIO for free through Virginia Tech. Others cannot. 
  2. Try registering EquatIO on another platform. Choose from the desktop application, the Google Chrome extension, or EquatIO mobile. 
  3. If you still can't register EquatIO, go to 4help.vt.edu, log in, and click Get Help. Explain your problem and submit. 

Trouble using EquatIO

  1. See Texthelp (the makers of EquatIO) EquatIO Documentation.
  2. Contact Texthelp Support

Can't convert to LaTeX in Microsoft Word
