Not open for further replies.


About a month ago I bought a new laptop, I set up a new email account with Outlook 2007 and everything ws working fine, until i clicked 'Send/Receive' yesterday and I received this error message:

" An OLE registration error occurred. The program is not correctly installed. Run Setup again for the program."

Does anyone have any ideas about how I can solve this problem, I use this Outlook 2007 account to send and receive business emails so I need it to be working!!!

Thank you!



I have the same problem, but it exists since installing Outlook 2007 and always occurs when I try to use the Search.

The issue is that the message asks me to reinstall the Windows Search, but I have done that already countless times w/o any success.

Please assist, thanks!



To fix the problem, simply close down outlook.

Open windows explorer and navigate to the following path:

C:\Documents and Settings\USERNAME\Application Data\Microsoft\Outlook

delete and clear all files located in the Outlook folder so that it is empty (username is the name you logged on with eg for me it would be C:\Documents and Settings\lilq\Application Data\Microsoft\Outlook).

Re-Open Outlook, and outlooks re-creates and updates it's data source and function correctly

This should fix the problem.

you can also try the following:
p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0cm;margin-bottom:.0001pt;font-size:12.0pt;font-family:Arial;} p {margin-right:0cm;margin-left:0cm;font-size:12.0pt;font-family:'Times New Roman';} @page Section1 {size:612.0pt 792.0pt;margin:72.0pt 90.0pt 72.0pt 90.0pt;} div.Section1 {page:Section1;}

regsvr32 %WINDIR%\system32\ole32.dll

Have fun

I had the same problem in both Outlook 2003 and 2007 when double clicking a mail message to move it to a folder. Deleting the files from the C:\Documents and settings\USERNAME\Application Data\Microsoft\Outlook did the trick.


Dear lilq,
Thanks for ur help, i have been facing this problem, since past 3 months, but now it got solved. Once again my heartiest thanks.,




Hello lilq,

1. I Have tried registering the OLE " regsvr32 %WINDIR%\system32\ole32.dll" , It doesnot help Me...

2. Deleted all files located in the Outlook folder C:\Documents and Settings\***" User name of your profile" ***\Application Data\Microsoft\Outlook) --- It works for me..........Now no OLE error.....

Hi Lilq,

Thank you very much for the solution posted. It works for me.....


Hi LilQ,

Thank you very much!

Deleting the files worked for me.




Great post! It took care of my problem as well.

However, I have to point out one thing. One of the files in that directory is your NK2 (*.NK2 with the most recent modified date) file that Outlook uses to store all of the email addresses it auto-completes as you begin typing someone's email address in the to/bc/cc fields. I actually deleted everything except for this file and the problem still went away AND I didn't lose my autocomplete addresses.

Thanks again!

I have a similar issue with a client workstation at work. I'm going to try registering the ole32.dll first. If that's doesn't work, I'll delete all the files in the outlook directory. If none of the above works, well, it's a full reinstall with a new profile. Hopefully deleting the files will do the trick." There's a time and place for that. The time is... Never. You can figure out the place on your own" .
