Delete 64-bit registry Key using 32-bit installer

Question

I have installer (InstallanyWhere 2013) that has feature to execute the batch file. I created the installer using 32 bit JRE.

I have two location:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Lock Configuration Tool (32 bit registry location)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Lock Configuration Tool (64 bit registry location)

Batch file code:

 cd\
cd c:\windows\system32
    reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ProjectName" /f

When above command executed then it point to 32 bit registry not the 64 bit registry. I know the reason the "HKEY_LOCAL_MACHINE\SOFTWARE" convert to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node so it point to 32 bit registry.

My question how to delete the 64 bit registry using 32 bit installer (internally use the batch file) via command prompt. Does command prompt provide any feature to point to 64 bit registry?

This one plagued us for while. You need to use the /reg:64 parameter. Source

Example:

reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ProjectName" /f /reg:64
