Michael,

In InstallShield, testing for a file's existence isn't so difficult. You simply use the Is() function like this:

Is(FILE_EXISTS, sTestPath ^ "Myfile.txt")

FILE_EXISTS is an IS constant for the Is() function. Obviously, it will return false if the file does not exist. Depending on the result, you should be able to either use the ParsePath() function to extract the path and set your TARGETDIR for installation, or simply call the abort command.

Hope that helps.

Laterness,
Jon
