I'm trying to install Paint Tool SAI ver.2 (64-bit) and it spits out a ton of errors. One in particular I also got when trying to install something unrelated so I want to try to figure it out before troubleshooting the rest. Here:
Code:
000d:err:wincodecs:PngEncoder_CreateInstance Failed writing PNG because unable to find libpng12.so.0
I followed the instructions given here and installed libpng12 & did
Code:
sudo ln -s /lib/i386-linux-gnu/libpng12.so.0  /usr/lib/libpng12.so.0
sudo ln -s /lib/x86_64-linux-gnu/libpng12.so.0  /usr/lib64/libpng12.so.0
which resulted in these 2 errors:
Code:
ln: failed to create symbolic link '/usr/lib/libpng12.so.0': File exists
ln: failed to create symbolic link '/usr/lib64/libpng12.so.0': No such file or directory
Ultimately it didn't fix the original error. Can someone help me figure out what these errors mean and what I need to do instead?

Ubuntu 18.04.1 LTS & Wine 4.0-rc5
