I have a question about finding if a specified app is installed on a machine or not.
I use:
RegOpenKeyEx(HKEY_CURRENT_USER, SUBKEYTOPATH, &H0, KEY_READ, dwKey) and on most machines get a return code of , which is fine, but on some machines I get a return code = 2 even if the specified app is installed on the machine. Any ideas on what a return code of 2 means? Any ideas on how do do it better?
