registry section has missing parameter ( INNO Help shows why )

Root key values with a suffix of 64 can only be used when Setup is running on 64-bit Windows, otherwise an error will occur. On an installation supporting both 32- and 64-bit architectures, it is possible to avoid the error by adding a Check: IsWin64 parameter, which will cause the entry to be silently skipped when running on 32-bit Windows.

so look to [registry] section of his script & add ;Check: IsWin64 to the end of those lines, will get rid of that error.
then save & recompile the script.
