Reading registry value's data with spaces - batch-file

Question

I am making a program. When installed, It will run a batch file which needs to know where the application folder is.
The installation wizard software I am using creates a registry key that represents the program's path, but "Program Files" has a space in it, so the batch output will be "C:\Program"
My current script is:
#echo off
setlocal ENABLEEXTENSIONS
set KEY_NAME="HKEY_LOCAL_MACHINE\Software\MarksRTZ\AV"
set VALUE_NAME=DataPath
FOR /F "usebackq skip=2 tokens=1-3" %%A IN (`REG QUERY %KEY_NAME% /v %VALUE_NAME% 2^>nul`) DO (
set ValueName=%%A
set ValueType=%%B
set ValueValue=%%C
)
if defined ValueName (
echo data "%ValueValue%"
echo name "%ValueName%"
echo type "%ValueType%"
) else (
echo Not found
)
The DataPath value is set to [APPDIR]\data on installation, [APPDIR] being the location the user selected.
But like I said, that script will always output C:\Program if [APPDIR] was set to something like C:\Program Files (x86)\MarksRTZ\AV\ in the installer (Which is actually the default)
How can I fix this?
I will also note; the batch file isn't the real program, It's going to be the simple script that launches the program in the correct working directory.

Next code snipped should work with tokens=1-2* and even with setlocal DISABLEEXTENSIONS:
rem ensure %ValueName% is not visible as it could be defined already!
set "ValueName="
FOR /F "usebackq skip=2 tokens=1-2*" %%A IN (
`REG QUERY %KEY_NAME% /v %VALUE_NAME% 2^>nul`) DO (
set "ValueName=%%A"
set "ValueType=%%B"
set "ValueValue=%%C"
)
if defined ValueName (
echo data "%ValueValue%"
echo name "%ValueName%"
echo type "%ValueType%"
) else (
echo Not found
)
