Bug ID: 44755
           Summary: reg.exe: does not provide /reg:64 switch in 64-bit
                    wineprefix
           Product: Wine
           Version: 3.4
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: registry
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

In a 64-bit prefix, the reg.exe command line switches /reg:32 and /reg:64
should be available to enable/disable registry redirection.

A command like `wine reg import /reg:64 test.reg` should be perfectly valid, to
prevent the imported keys from going somewhere in Wow6432Node, but instead it
gives the following error:

reg: Invalid syntax. Type "REG IMPORT /?" for help.

As far as I could figure out, there is no workaround other than manually
importing the keys in the regedit GUI (calling regedit from the command line 
with the registry file as an argument doesn't work), which makes importing keys
correctly not automatable.
