WiX: InstallUISequence + custom action - wix

Question

<InstallUISequence>
<Custom Action="myActionid"
Before="ExecuteAction">NOT Installed</Custom>
</InstallUISequence>
i use this to set when my customAction will run but it doesent seem to run when i want it to.
in verbrose log i see this

My action runs too soon i need it to run right before Execute action (or between the middle bold part and executeaction)
because after that the properties change and i cant get the right values
alternatively make the properties stop from changing that would also work.
the properties are copies of INSTALLDIR meaning i've copied BrowseDlg and made the installdir dialog into a dialog that asks for three paths i need for my program. i will post that code too if you think its necessary but it feels like i could be able to just specify when my custom action runs to get the right values!
thank you for answers :)

Answer 1

Alright i still dont know how to set mycustomAction to the specific runtime that i wanted but i dont need to anymore because i found out why my Properties like the INSTALLDIR was changed by costfinalize
i dont know the reason why it works this way but i had my directories with small letters in the id and then costfinalize changed them back to the default after the install sequence
so having all caps like this
<Directory Id="SPCSFOR" Name="Företag">
</Directory>
<Directory Id="SPCSGEM" Name="Gemensamma filer">
</Directory>
<Directory Id="VISMAADMIN" Name="SPCS Administration">
</Directory>
was the last piece of making my own InstallDirDlg working more like the original and the properties stays the way the user changes them with BrowseDlg
and after that it was easy for my to just set mycustomAction
<InstallExecuteSequence>
<Custom Action="myActionid"
After="InstallFinalize">NOT Installed</Custom>
</InstallExecuteSequence>
like that and read the properties from there instead and no problems trying to time it just right to get the values i wanted!
