First, I thank you for a brilliant program. This is by far the best, most useful sound font editor, IMHO.
I am running the program on three machines. The others are 64-bit machines with Windows 10, and everything works flawlessly with them. When I install Polyphone on my 32-bit machine (Windows 7), the menus are all in German. I tried re-installing and got the same result even when I installed the Spanish version. It's not a big problem for me, but I thought you should know about it.
Also, on the Windows 7 machine, I have to use version 2.1 because when I try to use 2.2 it gives me a message that it's not a Windows program.
Polyphone v2.2 package for windows 32 bit erroneously comes with 64bit vcruntime140.dll and msvcp140.dll.
Delete or replace those with 32 bit variants to get around.
