DateAdd returns a date, Session.Property must take a string, hence the type
mismatch error you were likely receiving.
Try this instead... Use FormatDateTime to convert your date object...
<CustomAction Id="CalcOldDate" Script="vbscript">
SUB CalcMigratorDate
Session.Property("OLDDATE") =
FormatDateTime(DateAdd("d",-30,DateValue(Now)))
End SUB
call CalcMigratorDate
</CustomAction>
<Standard disclaimer regarding script CAs goes here, though I didn't realize
WiX made them so darn easy to add/use!/>

Subject: [WiX-users] Date calculations
Hello,
In a custom action, I am going to run an exe with args. One of the args
is a date that is 30 days older than today. Could some let me know how
this could be done?
Here is how I am trying to solve this.
Create a property calle "OLDDATE"
Create a custom action that has vbscript which runs before the above the
exe's custom action.
My VBScript custom action looks like this. This is throwing an error. I
tried without set. No luck. Any way of fixing this and any other smart
of doing this ? Thanks in Advance
<CustomAction Id="CalcOldDate" Script="vbscript">
SUB CalcMigratorDate()
set Session.Property("OLDDATE") = DateAdd("d",-30,DateValue(Now))
End SUB
call CalcMigratorDate
</CustomAction>
