Hi all,
After many years of struggling with this, I have finally figured out the solution to getting the TekVisa Toolbars for Office running on modern Windows systems.:
Short version:
- Install the 32-bit versions of Microsoft Office, TekVISA, and the TekVISA Toolbars
- Manually copy the toolbar template files to %OFFICEROOT%\startup and \xlstart
- Add those directories as Trusted Locations to the Office Trust Center
Long version, with
step-by-step directions and links.

Please let us know if this helps!
