[wix-users] How to do a conditional FileSearch?

[Fyodor Koryazhkin]

Hi,
I see, sorry.
As far as I know there is no predefined order in AppSearch table (This is
the table that triggers all other searches). Also there is no condition.
If you need all the properties then you should search several times: first
time only for registry, the second time for registry and directory(nested)
and the third time for the file (Also nested). Every search you assign do
different property.
