Sorry desmoflex! I forgot to include the link to the patches at The Patches Scroll.

That would not be correct. To see whether or not Tactcom patch is already included, start EF2000 with its regular executable, ef2000 iirc. Then see internally whether you have the features you want from Tactcom. Is that clear? In other words, you may have a version already patched to the Tactcom level. Just don't use the tactcom.exe to launch the sim.
The best thing to do if when starting your various (NON WIN 95!) versions you learn that you do not have tactcom already installed, is to next learn exactly what version number (the patch or sim version of your different DOS EF2000 editions. Not the verbal description/language version, etc. - the version number. That way your will know exactly what you have and what patch - if any at all - is needed before for your experiment with Glide.
But let me ask this: have you tried the modded Glide dosbox for EF2000 yet? On any of your DOS versions? What could it hurt?
I am not clear on whether you have tried applying the Graphics + patch to your DOS versions. That is the patch that - if not already applied to your versions, you will need in order to use the modded DOSBOX for EF2000 3Dfx version. That patch is at the top of the page I linked for you, above.
