Hi,


I am developing a setup for a product using InstallShield Professional v5.5.
From my setup, I want to check whether Microsoft Visio and Oracle Client exits on the target computer and write the same message into the log file.

1. How do i know the existence of these softwares through my script.

2.How to write the appropriate message into the log file.


Thanks
Jaya

To see if Visio is on the computer check for the existence of the following registry key:

HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Visio

Under this key there is a string value named "CurrentlyRegisteredVersion", whose value is the version installed on the computer.

I suspect the registry key for Oracle might depend on the version installed, so I can't help you with that.

As far as writing to a log file, here is some sample code from the InstallShield help files:

OpenFileMode(FILE_MODE_APPEND);
OpenFile(nvFileHandle, "C:\\Example", "Myfile.txt");
WriteLine(nvFileHandle, "Line I am adding to my file.");

Note: if you have just created a file using the CreateFile function, do not open the file. It is already open in append mode.
