WiX's candle.exe/light.exe are 32-bit. A SYSTEM-run runner has %LOCALAPPDATA% under C:\Windows\system32\config\systemprofile, where Tauri caches the WiX toolset — and WOW64 redirection sends 32-bit processes reading System32 to SysWOW64, which has no such directory. The CLR then fails to start with 0x80131700 and Tauri reports only "failed to run candle.exe". Verified: the same binary and identity exits 0 from C:\wixtest and 0x80131700 from the systemprofile path. Pointing LOCALAPPDATA outside System32 avoids redirection, needs no stored credential, and is a no-op for runners already running as a normal user.
