[wix-users] Set property from custom action?

[Hoover, Jacob]

<InstallExecuteSequence>
<Custom Action="MyCASetLocalAppData" Before="CostFinalize">Not
Installed OR UPGRADINGPRODUCTCODE</Custom>

It only runs in the second sequence, because that's where you told it to run.

Have a look at firstSequence in

https://wixtoolset.org/documentation/manual/v3/xsd/wix/customaction.html


Also ensure any properties you want to pass from client to server are flagged secure and are defined in all upper case.

https://wixtoolset.org/documentation/manual/v3/xsd/wix/property.html

The one thing I am not certain of is if a directory ref is treated like a secure custom property or not.
