getMachineInnoExec static method

File? getMachineInnoExec({ bool throwIfNotFound = true, })

Locates a machine-wide or per-user install of Inno Setup (ISCC.exe).

Checks the system directory (innoSysDirPath) then the user directory (innoUserDirPath). Installs whose reported version is below minSupportedVersion are treated as if they don't exist (left in place, never used). When throwIfNotFound is true (the default), prints a guidance link via CliLogger and exits if no usable install is found or it appears corrupted; otherwise returns null.

          "checkout our docs on how to correctly install it:\n"

    if (version != null &&
        compareVersions(version, minSupportedVersion) < 0) {
      if (throwIfNotFound) {
