New Post: Session variables etc.

Hi

Still I don't get it.

I try to access the property "WixUI_InstallMode" (which I can see being set in the logfile when running in mondo mode) - but it's empty.

I define my managed action like the following (it becomes elevated and by that deferred as I understand it)

, new ManagedAction(@"OnPreInstall", Return.check, When.After, Step.InstallInitialize, Condition.NOT_BeingRemoved)
{

         UsesProperties = "D_WixUI_InstallMode=[WixUI_InstallMode], EVENTLOGNAME=[EVENTLOGNAME], INSTALLDIR=[INSTALLDIR], VERSION=[VERSION],        PRODUCTNAME=[PRODUCTNAME], PRODUCTEXECONFIG=[PRODUCTEXECONFIG], TPCSERVERURL=[TPCSERVERURL], VCPAGENTURL=[VCPAGENTURL], LOCALE=[LOCALE]"

}

No matter what the "D_WixUI_InstallMode" or WixUI_InstallMode is empty - I can accesse all other defined (my own) properties.

What is the rigth way to access variables like WixUI_InstallMode, LicenceAccepted etc.
