MSCOMCT2.OCX registration error "ClassFactory cannot supply requestedclass"

[Greg Lovern]

I used the datepicker control from MSCOMCT2.OCX in Excel VBA, and I
ensure that MSCOMCT2.OCX is present and registered on each computer.
It works fine on most computers.

But now on a new computer I can't register it. When I try to register
it (with regsvr32), I get the error:

System Error &H80040111 (-2147221231). ClassFactory cannot supply
requested class

How can I get it to register? Normally regsvr32 has no problem
registering MSCOMCT2.OCX.


(I know that it is not registered because when I try to instantiate
the datepicker control, I get the error "Object library invalid or
contains references to object definitions that could not be found")


Thanks,

Greg

Hi Greg

Would this new wonder machine by any chance be running the marvellous very
safe Windows Vista operating system ?

If so, do not try to place and register anything in the Windows/system32
catalog or anywhere near system files, it assumes you are a madman and
refuses to do it even with an admin account. Try putting it in a "normal"
innnocent looking folder and regsvr32 it from there (full path).

HTH. Best wishes Harald
