function EnableFsRedirection(const Enable: Boolean): Boolean;
Function removed in 7.0.
Use support function ApplyPathRedirRulesForCurrentProcess instead, or a 64-bit installer.
32-bit installers can also use {sysnative} instead.
Use support functions ExecWithNativeSysDir, ExecAndLogOutputWithNativeSysDir, or ExecAndCaptureOutputWithNativeSysDir to launch an executable located in the 64-bit System directory from a 32-bit installer.
