1.6 launcher mods won't work with 1.5.2 profile

So I had schematica on my 1.5.2 launcher and now I upgraded to 1.6.2 installed forge and schematica for 1.6.2

The issue is forge comes up as its own profile in version 1.6.2 so I have 3 profiles

1.6.2, 1.5.2, and forge(1.6.2)

How do I make a 1.5.2 forge profile on the 1.6.2 launcher

Sadly, you don't.
The new launcher changed the way that mods are installed from use of the "bin" folder to the "versions" folder.
Unless you still have the old launcher and the old bin folder to install mods the old way, there isn't much to be done.

I have a 1.5.2 backup of all the files just in case something happened

So what do I do now

Is it the original "bin" folder and all it's contents?
The old launcher as well?

Not the old launcher but the bin folder

You will need the old launcher as well, otherwise when you play 1.5 in the new launcher, it'll use the "versions" folder instead, even if you have the old files.
Once you have the old launcher and the old "bin" folder you should be able to install mods the way you did before.

I use magic launcher and can play 1.5.2 with mods no problem. Try getting that and using it to install your mods.

Magic launcher I will try that

Click it and Profit
