InstallAware

I built an IA6.6 project using the Update 2.0 script for my app (lets call it MyInstaller.exe). Some user's, when re-installing my application are getting an error:

Runtime error in setup script:
Line 280: Attempting to get value of undefined variable UPDATE_CONFIGURED.

I need to be able to delete this stored variable on the user's computer so that they can install my application. Where would this persistent variable be stored on their computer?
myahe.dat?
MyInstaller.dat (if there is such a file)?
Registry (if so, where?)?

I've read the forum posts on myahe.dat but they appear to relate to the installation of IA itself. I've searched my own computer and read the help files. I'm still stuck.


... Fig

(p.s. since I released the product I have upgraded to IA7).

The values for persistent variables are stored in both MyInstaller.dat and MyInstaller.exe which are located at the uninstall folder. However, I am not sure what would happen if you remove them. For sure, if you modify the exe file, it will crash, but cannot tell about the .dat file.

Thanks!

So, to fix this I should be able to just remove the uninstall folder? That should remove the MyInstaller.dat *and* MyInstaller.exe files (assuming the project is named 'MyInstaller').

It appears these folders were not removed during the uninstall on *some* of my user's computers.

Does the the uninstall folder have a CSIDL of CSIDL_COMMONAPPDATA ?

On XP C::\\Document and Settings\\All Users\\Application Data\\<install_guid>

On Vista C:\\Program Data\\<install_guid>

Deleting the uninstall folder did not work. I tested using my development computer. Subsequent installation attempts still resulted in

"Line xxx, unable to find variable UPDATE_CONFIGURED"

After cancelling the error there was an empty product guid folder (C:\\Documents and Settings\\All Users\\Application Data\\<guid>) as if the installer was trying to find the "MyInstaller.dat" file there, but could not.

I also did a test by copying the IA "myahe.dat" file into the above folder but renaming it "MyInstaller.dat". Afterwards when I ran my install it offerred the uninstall choices. This worked and I was able to then reinstall my app.

This doesn't help me with client computers, though. What needs to be cleaned up on a target computer to prevent the unable to define UPDATE_CONFIGURED message?
