FlashPatcher VS Launcher

I'm stubbornly sticking with classic, period, until the end of time. However, you might have some luck with this or this. Read carefully, consider what you want to do in regards to your browser, your browser's ability to work with flash, etc.

So far, I have found FlashPatcher, a tool that removes the kill switch from Flash Player 32.0.0.465, along with links to the installers.

If you have a way to get access to a desktop computer that can run a browser that still allows flash and/or run a program that will remove the "time bomb" from flash player and use the "classic" (flash) based customization, you'll be able to dress up your pet normally.

Options are 1) various workarounds to trick Flash into working on your computer, 2) run this GitHub program to remove the "time bomb" from Flash on your computer*, or 3) Use a browser that will still allow Flash, I've heard one called PaleMoon recommended on this subreddit.

I was able to get Flash working for me on my desktop PC without messing with time settings by using this github program, but I will probably have to go to an old browser eventually once Firefox ESR starts actively blocking Flash.

Waterfox and Basilisk are browsers that still support Flash. You can install Flash with this https://github.com/KuromeSan/FlashPatcher/releases or use this old version of Flash https://archive.org/download/flashplayerarchivedversions2/357/fp_32.0.0.344_archive.zip

If you want to revive Flash: https://github.com/KuromeSan/FlashPatcher/releases . Enjoy :).

Here is a link to Modloader for MCb173. It needs adding directly into the minecraft.jar file, however if you use a launcher like MultiMC, which you can find here: https://multimc.org/ then there is an option to 'add to minecraft jar file' which does the same thing.

I used to have this issue lots, and it was due to my internet being too restrictive. The Minecraft Launcher was refusing to open, and I fixed it by messing with the restrictions until it worked. Hopefully this helps :) if all else fails of course, try just reinstalling it! I’m sure that all your config files don’t get affected by reinstalling it, but just in case make a backup. And if all ELSE ELSE fails, you could switch to a completely different launcher, like MultiMC! Good luck!

If you are willing to try out the launcher - MultiMC which you can find here (there is a Mac option available) : https://multimc.org/ then I have put together an MCb173 pack that has been made for MultiMC. You just use the 'import from zip' option.

Download MultiMC from their official site https://multimc.org/

Others than that, if you insist, you can take a look at the launcher which u/reginakinhi provided or find others on the internet (GitHub for example). Since PrismLauncher is written in C++, and if you are not familiar with it, you should see other launcher as well. Or else https://github.com/MultiMC/Launcher is an alternate.

The best way to experience beta 173 is to play beta 173, and perhaps add some mods to it a little later. One of the better launchers to use for old versions and for playing modded is to use the MultiMC launcher which you can find here: https://multimc.org/

This will only assist if you are using MultiMC as your Minecraft launcher as it is a MultiMC instance which you can use the 'import from zip' option. MultiMC can be found here: https://multimc.org/ It includes IC2 1337 with several add-on mods which have also been back-ported to work with it, such as the Thermometer, Advanced machines, etc. You can disable the add-ons you do not wish included. There is also buildcraft and redpower added as well.
