A programmatic identifier (ProgID) is a registry entry that can be associated with a CLSID. Like the CLSID, the ProgID identifies a class but with less precision because it is not guaranteed to be globally unique.
The CLSID key contains information used by the default COM handler to return information about a class when it is in the running state. To obtain a CLSID for your application, you can use the Uuidgen.exe, or use the CoCreateGuid function. The CLSID is a 128-bit number, in hex, within a pair of curly braces.
CLSID is an abbreviation for class identifier, in the same way that GUID is an abbreviation for globally unique identifier. Both abbreviations refer to a 128-bit integer with a low statistical likelihood of being duplicated so that it can be used as a unique identifier across computers and networks.
The Class ID, or CLSID, is a serial number that represents a unique ID for any application component in Windows. In practice, this means all registry entries for an application component can usually be found under the registry key HKEY_CLASSES_ROOT\CLSID\{CLSID value}.
Search for the program, folder or library name in regedit. You will probably find several occurrences but one of them should tell you the CLSID.
A CLSID is a globally unique identifier that identifies a COM class object. If your server or container allows linking to its embedded objects, you need to register a CLSID for each supported class of objects.

If you have a CLSID {} you can take a look at the registry key HKEY_CLASSES_ROOT\CLSID\{}\ . The default value for the registry key will give you a description of the CLSID. Other values under the key will give you more information like the DLL that implements the interface and a short name (program ID).
