Custom prerequisites registry condition

I'm trying to install C++ redist 2015-2019 bundle as a custom prerequisite. Before that, I need to check if the bundle isn't installed yet or it has a lower version. The problem is that depending on the bundle version the registry key name can vary. See the example below:

  • HKEY_CLASSES_ROOT\Installer\Dependencies\VC,redist.x86,x86,14.24,bundle
  • HKEY_CLASSES_ROOT\Installer\Dependencies\VC,redist.x86,x86,14.27,bundle

So, apparently, I need some kind of wildcard in the key filed in order to have the ability to check value under different keys.

 

What options do we have to do so?
