VB6 - embedded report load error - class not found

I attempted to load a Visual Basic 6 project with 5 embedded reports and received an error for each, stating that it could not be loaded.

The error log for each report reads as follows:
Line 2: Class {BD4B4E61-F7B8-11D0-964D-00A0C9273C2A} of control BCR_5Yr was not a loaded control class.
Line 0: The file C:\Clients\profac\working\svn_repos\fpm\trunk\BCR_5Yr.Dsr could not be loaded.
(Same message for each, only the name of the .dsr changed.)

The project's .vbp file has a class that is very close, "BD4B4E53-F7B8-11D0-964D-00A0C9273C2A", the difference in the first group, which ends in "E53" rather than "E61" - the numbers are otherwise identical. The class number in the .vbp refers to craxdui.dll, the Crystal Reports 9 library.

Searched the registry for the key "BD4B4E61-F7B8-11D0-964D-00A0C9273C2A" , and found this (broken at the backslash to avoid a wordwrap problem):

HKEY_LOCAL_MACHINE\
   SOFTWARE\
      Classes\
         CLSID\{BD4B4E61-F7B8-11D0-964D-00A0C9273C2A}\
            TypeLib
	    Default:{BD4B4E53-F7B8-11D0-964D-00A0C9273C2A}

Now I seem to have some options:

1. Change this default setting to BD4B4E61-F7B8-11D0-964D-00A0C9273C2A

2. Change the setting in the .vbp file to
	BD4B4E61-F7B8-11D0-964D-00A0C9273C2A

3. Change the setting within the .dsr files to
	BD4B4E53-F7B8-11D0-964D-00A0C9273C2A

4. Forget all this, uninstall Crystal Reports, then reinstall and patch to latest level.

5. Check the Windows XP restore points and jump back a couple of days.

Suggestions will be welcome.
