Unable to load DLL 'OraOps10.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

That pesky problem has reared its ugly head again!
I remembered that its a permissions problem but forgot the wrinkle where you have to REMOVE THE PERMISSION AND THEN GIVE IT BACK.

See bold type below:

Solution Description:
Follow these steps to restore default access to Read and Execute access for Windows authenticated users:

2. Launch Windows Explorer from the Start Menu.
3. Navigate to the ORACLE_HOME directory and right click on the ORACLE_HOME folder icon.
4. Select the "Properties" option from the drop down list. A "Properties" window should appear.
5. Click on the "Security" tab on the "Properties" window.
6. Click on Autheticated Users in the "Name" list.
7. Uncheck the "Read and Execute" box in the "Permissions" list. This box will be under the "Allow" column.
8. Check the "Read and Execute" box. This is the box you just unchecked.
