How do I install Thermal Foundation with Forge?

I've already installed many 1.12.2 mods with Forge.

But if I want to install Thermal Foundation, cofh Core and cofh world with forge, after opening Minecraft the message comes up: An unofficial version of Minecraft is being used. I'm then thrown back on the launcher.

As far as I know I use the right versions and even when loading it shows me no errors "wrong version etc." On.

Do I need vlt to install thermal foundation nor any other mods?

Or what could be the mistake?

Otherwise:

Are there any other mods the ores etc (if possible no machines) and add compatible with Tinkers construct (ie ores such as aluminum, copper, lead…)?

(Because TiCo adds in the upper world no ores, ornies and pebbles)

If yes, which mods are suitable? (For 1.12.2)

An unofficial version of Minecraft will be used

Sounds like something is going wrong with user authentication.

Do you have the launcher directly from Minecraft.net? And also uses your LogIn data from the purchase? This is at least not an error message, which is caused by missing mods, or incompatible mods.

If necessary reload the launcher again. Save your Minecraft directory .minecraft and delete it as a precaution. Try it again.

You can also try another forge version, but do not think the news comes from it.

All other mods work too…

And I have minecraft properly installed and logged on .net.

But I will reinstall the launcher again.

Please write me the whole version numbers (Forge / and also the modversions) Then I'll try the combination. Forge had indeed an update to a new version number, If you have the latest Forge, the vlt is not compatible with the mods… Or YOU try an older / other version of Forge

As usual, the log would make sense to determine the error. Without this one can only guess.
