如何在WiX中删除新版本后保留以前版本的文件关联？

I have Product A with Versions 1.0.0 and V2.0.0 each associated with file type xyz (to executable product.exe) using WiX File association. When Product A V1.0.0 is installed, then file extension xyz is associated. Next, I install Product A V2.0.0, now the file xyz is associated with Product A V2.0.0. File association is overridden as expected or vice-versa if 2.0.0 is installed first and later V1.0.0.I have Product A with Versions 1.0.0 and V2.0.0
