Is Team Developer 3.1 compatible with Windows 10?
No, no version listed on the official website of the developer is compatible with Windows 10. The latest Windows supported is Windows 8.1 Pro 64bit. The 3.1 version is compatible with older versions of Windows. I recommend checking the official table to obtain additional data.
