Installer forge can only be used for the latest version of forge for 1.12.2 and for 1.13+. Use Forge Universal for anything lower.

Did you include installer forge or universal forge?

Logging in with a microsoft account works quite a bit different than the old Mojang Email way. Blame Mojang/Microsoft for that, they promised a solution for months, then just stopped caring about it.

Do not add Optifine to a 1.7.10 modpack that contains Fastcraft, as you get this crash.

It doesn't freeze, it is waiting for the reply from the browser that pops up and where you actually log in to.

The particular error report you provided stated the following: Memory: 4k page, physical 8338684k(4094880k free), swap 8338684k(2480228k free) Which is less than (the error): Native memory allocation (mmap) failed to map 4294967296 bytes for Failed to commit pages from 0 of length 1048576 By about 100 MB to be exact. Technic works a bit different than the regular launcher in that it reserves the RAM you give it, instead of just slowly grabbing more and more and then causing issues, like regular minecraft.

If you try to allocate 4 GB, make sure you have that 4 GB available to be allocated. Otherwise, you get this.

Then use the recommended version, not the latest.

Why would you want to play that version?

Tekkit does not run with anything higher than java 8. This particular error points out that you are using a java version higher than 8.

I'll assume you are on Forge Recommended/Latest for 1.12.2, which require you to use the installer instead of the universal. Treat the installer just like you would with the universal.

You included the Forge installer, not the Forge universal like you should. Forge installer is only for Forge 2854 and up (MC 1.12.2+). And this belongs in Platform Pagoda.

Irrelevant review as this isn't directed at any server posted in this way.

Don't zip the folder containing your modpack folders, zip the bin/config/mods folders directly.

This belongs in Platform Pagoda. If you are using Forge 2854/2855, you will have to use and rename the installer instead of the universal. Do not open the installer, rename it as-is.

Have you considered posting a log, just like the person in that old thread did?

This requires Universal Electricity as a mod as well, a version that's newer than the one included, which then causes more crashes due to mod incompatibilities with other mod versions, you could probably fix that as well by updating more mods, and at some point its no longer tekkit. These two mods were not meant to be added to TekkitMain.

The bug you show in your video is actually a slightly different one, but with a known cause: If you don't set a recommended java, but do set recommended RAM, you get that particular error.

That got me the warning screen instead, hence my confusion on the matter.

I can only get this to trigger the moment I go 1 MB above 16 GB (thus, 16385, 16384 gives the warning). Is this the same in your case, or are there other values that didn't work?

Had you gone and searched the issue, you would've found so many. With so many of my same answer. You used Forge 2855 universal. Don't. Either use 2855 installer renamed as-is to modpack.jar, or use 2847 universal, renamed to modpack.jar.

Out of interest, what's the required minimum memory for this modpack?

If they linked it to their microsoft account and that account is considered underaged, you can't use the launcher. Courtesy of microsoft, really. Such a pain.

Bugger off with your cracked launcher.
