Installscript GUID on install

[turbokitty]

I have an installscript install that is installing with a random guid. This guid is used for this folder:
C:\Program Files\InstallShield Installation Information\{09713114-FA89-44B5-801E-A605FEDFFBD6}

And this registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{09713114-FA89-44B5-801E-A605FEDFFBD6}

The guid "{09713114-FA89-44B5-801E-A605FEDFFBD6}" is different each time it installs. This is a huge headache for me because it won't uninstall silently and I need to create a script that uninstalls it. I can't find the A/R entry with my script because it's always different.

Is there a way to hard-code this GUID?

Thanks.

That seems strange---is it a multi-instance InstallScript project? The value of PRODUCT_GUID is normally used as a constant GUID for the uninstall key.
