Upgrade from old installer to new installer

What you can do is: read registry values and search from files in the new installer to detect the install location of the old version, then overwrite existing files with the newer version. You should also remove the old uninstall registry entry. As an alternative you can invoke the uninstaller of the old version from the new setup.

I am in the same boat, and have tried many routes to this destination, with no luck. I've tried to search for the registry key that I have the installation path stored in, but since the previous developer created this key with a value of "c:\program files\company name\folder" including the " ", InstallShield doesn't recognize it as a directory when I search for it via AppSearch, RegLocator, Signature, and DrLocator tables.
So, I tried an alternate method, Signature, DrLocator, and AppSearch, looking for the file, in a folder, and then installing to that folder. No luck here either.
Since the end user could have installed to a different location than our suggested one, we need to search for it and install the updated .dll file to that same location.
Thanks in advance!
