Hi Fred,
Started testing 7.8.0 version on AMD Windows 11 x64.
installed first time over previous version and not updated the main executable (7.7.8), also when run the installer gives me the installation folder in C:\Program Files (x86)\eFMer\TThrottle instead of C:\Program Files\eFMer\TThrottle, just corrected the path and installed in the proper folder, but remained the old executable.
removed the files inside the folder C:\Program Files\eFMer\TThrottle and run again the installer, and this time the complete program was installed.
regarding the version for windows ARM64, for the CPU temperature display I'm using app HotCPU (just for info), no throttling could be done.
