We have two products - a beginner version and a full-featured version. The files in both versions all have exactly the same names, but one of the files is different internally, which gives the different versions.
The problem is, if a user installs the full-featured version on top of the beginner version, InstallShield thinks the files are the same, and thus doesn't actually install the full-featured version.
How can I distinguish these two identically-named files (one full-featured version, the other beginner version) and then convince InstallShield DevStudio 9 that if the user installs the full-featured on top of the beginner, to go ahead and upgrade the file?
Thanks,
Chris

Wth function GetFileInfo you can get the file size or the MD5 check sum. This should enable you to tell the files apart. Then you could delete/rename the existing file to let the new file install, or set the component to "always overwrite" or overwrite same or older version.
