reach parent directory of modified INSTALLDIR

[sudan...@gmail.com]

Hi,

I am trying to modify the INSTALLDIR property. For this, I used the
Custom Action Type 35, which allows me to set a directory with a value
(another property, env variable, or component directory name).

So i created a property in the AppSearch table and read the value from
a Registry key (appropriate entry made in RegLocator table)

The value that is being picked up from the registry is, say, G:\temp
\ABC while I want to set INSTALLDIR to the value G:\temp.

So I need to reach the parent directory.

Could anyone give me any pointers on how to do this?

Thanks in advance,
Komal.
