On the other hand, I try to reduce the number of createobjects to test whether something is installed

They take time, especially if you have them in a menu skip for clause

So, the first time I need info (reg class, regex, ...) I instantiate the class and cache the result. The next time, I take it from the cache

So, one createobject('Excel.application') does not matter too much
