[wix-users] Run custom action only during modify

[Satya]

Hi Edwin and Vladimir,

I haven't tried the suggestions shared by you yet. Before that I would like
to know whether it is possible to use "WixUI_InstallMode" property. I
observed that this private property holds the correct value based on the
installation type.

Example:
MSI (c) (1C:5C) [16:58:07:499]: PROPERTY CHANGE: Adding WixUI_InstallMode
property. Its value is 'Change'.

Can we use this property? I tried to read it like other public properties
but it's not working.

Regards,
Satya
