Action “Set Registry Value”

`Action.RegValType = rtExpandString`  
returns an error

> Error Executing script : AfterAction  
> Laufzeitfehler in Microsoft VBScript  
> Typenkonflikt: ‘Action.RegValType’

but this works  
`Action.RegValType = rtString`

It’s a bug, rtExpandString was not registered with the scripting engine (it was probably added after the others and the dev forgot about scripting support).

You can work around it for now by replacing it with it’s value : 4

This will be fixed in the next update.
