Change maximum allowed configuration file size [IIS Express 10/Windows 10]

Question

After adding multiple entries to a redirect map in a linked config file, I get the following error on IIS Express 10 on Windows 10 (64 bit, but IIS Express is running 32-bit):

"Can not read configuration file because it exceed the maximum file size"

I've tried adding a Configuration key to the registry, setting a MaxWebConfigFileSizeInKB value of 512 under HKLM/Software/Microsoft/IISExpress/10.0/mimic/Configuration:

Any idea on how to enable configuration files larger than 250 KB for IIS Express on Windows 10? Cheers!

Basically, I had to add the the MaxWebConfigFileSizeInKB value under: HKLM/HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\IISExpress\10.0\mimic\Configuration
