How can I write my for loop and reg query to return data containing spaces?

Question

When I run the following in a batch file:

for /F "tokens=3" %%A in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 3990" /v "InstallLocation" 2^>nul') DO (SET INSTALL_LOCATION=%%A)

The value of INSTALL_LOCATION is C:\Program, rather than an expected value of C:\Program Files (x86)\Steam\steamapps\common\Sid Meier's Civilization IV Warlords.

I think this is a problem with my for loop as opposed to reg query, and also I suspect it is caused by the data for that key containing spaces.

How can I get the expected value, please?

My OS is Windows 11 and the script is being executed in CMD.

Thanks!
