I need to use LongPathToShortPath on INSTALLDIR for a registry entry.  The problem is that the files/folders do not exist until after ALL the sequences take place (by design?).
I can get the desired value (MessageBox), but I can not write it.
How can I retrieve INSTALLDIR's short filename and MsiSetProperty for a write to the registry ( [SHORTFILENAME]\hKey\value )?  Do I use deferred execution?  If so, DocID#104413 is confussing to me.

Thank You

Hi Cygnusx1,
I think you can create immediately CA to retrieve Windows Installer property INSTALLDIR (use MsiGetProperty(...)). Then change it and set another yours property like SHORTFILENAME (use MsiSetProperty). And use this property in IDE "Configure the targetSystem\Registry" like
"YoursValue     SHORTFILENAME"
Good luck.
