Hi to all,
I notice there is a difference between the uninstallation string stored in UNINST installscript constant and the uninstallation string stored in the registry area under:
"HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\{GUID}".
In details in the first one there is a -uninst field missing in the second one.
For example:
string in UNINST is:

UNINST constant, what is it?

string under "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\{GUID}" is:

| RunDll32 C:\PROGRA~1\COMMON~1\INSTAL~1\engine\6\INTEL3~1\Ctor.dll,LaunchSetup "C:\Program Files\InstallShield Installation Information\{GUID}\setup.exe" -l0x0 |
anyone knows what -uninst do during uninstallation procedure?
I guess it force the uninstallation skipping the execution of possible script.
Thanks to all,
ciao Giuseppe

This is in the docs for UNINST in version 11.5, I guess it also applies to version 6:

It contains the command line that launches the copy of Setup.exe that was placed on the target system to perform uninstallation; the command line includes Setup.exe's -uninst option, which runs the setup as an uninstallation that prompts the user appropriately but does not execute any script code. |

Thanks a lot!
The IS6 Help is less clear since I found:

| This system variable is provided for compatibility with previous versions of InstallShield. It contains the command line that will launch the copy of Setup.exe that was placed on the target system to perform uninstallation. This command line is placed in the appropriate registry value by the DeinstallStart function, which is provided for compatibility with previous versions of InstallShield. The value of this system variable is shared among object scripts and between object scripts and the main setup script. The value you assign to this system variable in any script is the value it has in the subsequently executed code in any script (until its value is explicitly reset). You can append your own custom command line switches to UNINSTALL for processing by your script's uninstallation code. If you do so, and you change the value of the system variable DISK1TARGET, be sure to change DISK1TARGET before appending to UNINSTALL; UNINSTALL incorporates DISK1TARGET and is automatically changed when you change DISK1TARGET. |
Then, honestly I didn't understand what's happen to script code.
Ciao,
