Yes, there are alternative ways to install Textease on a Windows 10 PC. One suggestion would be to check if there is a compatible 64-bit version available for download from the official Textease website. If not, you can try running the 16-bit version in compatibility mode by right-clicking on the setup file, selecting "Properties," and then choosing a compatibility mode such as Windows XP. Another option would be to use virtualization software like VMware or VirtualBox to run an older version of Windows with Textease installed.
