I have Vista Home Premium 2-Bit.
When I try to launch Duplicate Cleaner (a free file duplicates finder),
as non-administrator. It launches OK (without UAC). But of course, some
duplicate files cannot be deleted because DC is running non-admin.
If I try to launch as administrator, I get UAC and: "Run-time error
'339': Component MSCOMCTL.OCX not correctly registered."
Here are my troubleshooting steps:
- Search C drive for all copies of MSCOMCTL.OCX. Only one copy in
System32.
- Download and install MS VB6 Common Controls from MS site.
- Launch DC non-admin. OK. (But there is no UAC dialog)
- Close and relaunch DC as admin. Get UAC and error 339.
- Rename MSCOMCTL.OCX to MSCOMCTL.OCX$
- Launch DC non-admin. I get 3 messages:
. . o The UAC dialog (which I didn't get
previously!! See above.)
. . o Msg "Feature not available. Insert Dell CD."
. . o Error 339
- Note that I did not insert Dell CD until I also tried to launch DC
as admin.
- Try to launch DC as admin. Get UAC and error 339.
- Retry to launch non-admin, but this time insert the Dell CD when
prompted.
- The Dell installer ran, and DC was launched correctly with no
further messages (and no UAC).
- There's a new copy of MSCOMCTL.OCX in System32.
- Close DC.
- Try to launch CD as admin. Get UAC. Click Allow. Get error 339.
Here's some interesting points about the previous:
- If MSCOMCTL.OCX is available, there is no UAC for DC as non-admin.
- If MSCOMCTL.OCX is *not* available, there *is* UAC for DC as
non-admin. (I'm no techie, but I don't understand this.)
- As non-admin, there is no error 339, but as admin I get error 339.
Can anyone help with this mess?
