Browse to HKEY_CLASSES_ROOT\CLSID\0006F03A-0000-0000-C000-000000000046 and look at the keys on the right and see what they are referencing.
You may need to look for a key called 0006F030-0000-0000-C000-000000000046 which will have 2 or more sub entries.
I don't have the info infront of me now but if you have a key called Inproserver32 or something similar post it's name as it may need to be deleted. Dont delete anything until you have backed up your registry and checked back here first with your results.
All fixes below do at your own risk, if you are not sure, speak to an IT consultant.
I had an couple of examples of this in the last week, one was fixed by removing the Inproserver32 (or something named similar as above), one by detect and repair in Outlook and the other by re registering redemption.dll
Another fix I have had in the past is to rebuild normal.dot:
Close Word / Outlook / Act
Seach the Pc for normal.dot (search in hidden files/ sub folders/ system files)
Rename any instance to normal.old
To re register redemption.dll
Start > Run > cmd
type: cd c:\program files\act\act for windows\ <hit the eneter key>
regsvr32 redemption.dll <hit the eneter key>
You should get a message saying the file has been registered. Click OK.
Restart the PC
Before opening act or outlook search the PC for a file called extend.dat (you will need to search hidden files and folders/sub folders/ system files)
I did the detect and repair and that seems to have done the trick. I'll keep an eye on it. Incidentally, this is a remote user who comes into the office every now and then. It was only his laptop that was doing it. I'm connected via the LAN and have not had this issue.
