When I try to open a contact in BCM it giver error "Cannot open this item. Some of the needed controls may not be registered". This results in that I cannot open the contact to edit. This is a new error as I have been using BCM for a long time. Can someone help, please?

Hi,

This issue may occur after uninstalling the 64-bit versions of Outlook 2010 and Business Contact Manager 2010, then installing the 32-bit versions. This results in incorrect values remaining in the the following registry keys:

HKEY_CLASSES_ROOT\TypeLib\{00062FFF-0000-0000-C000-000000000046}\9.4\0\win64

HKEY_CLASSES_ROOT\TypeLib\{FB0E72B9-41D3-46FC-9593-0846ECA9E143}\1.0\0\win64\(Default)

If it's your scenario, please try the fix below:
