Unable to load oci.dll

Had a problem in office with the oci.dll

In short, the oracle folder in the server has not enough permission. Perhaps, there is enough permission but somehow it is nto inherited down to the sub folders etc.

Found a fix and it is simply to re-apply the permission for the folder.

Steps below

Information from here.

1. Log on to Windows as a user with Administrator privileges.
2. Launch Windows Explorer from the Start Menu and and navigate to the ORACLE_HOME folder. This is typically the "Ora92" folder under the "Oracle" folder (i.e. D:\Oracle\Ora92) in Oracle9iR2 or "Client_1" folder under the "Oracle\product\10.1.0" folder (i.e. D:\Oracle\product \10.1.0\Client_1) in Oracle10gR1.
3. Right-click on the ORACLE_HOME folder and choose the "Properties" option from the drop down list. A "Properties" window should appear.
4. Click on the "Security" tab of the "Properties" window. NOTE: If you are running Windows XP and do not have a "Security" tab please do the following:
(a) Open "Folder Options" in your Control Panel. (
(b) Choose the "View" tab.
(c) Under "Advanced Settings" uncheck the option "Use simple file sharing (Recommended)". The "Security" tab should now be available.
5. Click on "Authenticated Users" item in the "Name" list (on Windows XP the "Name" list is called "Group or user names").
6. Uncheck the "Read and Execute" box in the "Permissions" list under the "Allow" column (on Windows XP the "Permissions" list is called "Permissions for Authenticated Users").
7. Re-check the "Read and Execute" box under the "Allow" column (this is the box you just unchecked).
8. Click the "Advanced" button and in the "Permission Entries" list make sure you see the "Authenticated Users" listed there with: Permission = Read & Execute Apply To = This folder, subfolders and files If this is NOT the case, edit that line and make sure the "Apply onto" drop-down box is set to "This folder, subfolders and files". This should already be set properly but it is important that you verify this.
9. Click the "Ok" button until you close out all of the security properties windows. The cursor may present the hour glass for a few seconds as it applies the permissions you just changed to all subfolders and files.
10. Reboot your computer to assure that these changes have taken effect.
11. Re-execute the application and it should now work.
NOTE: If the problem continues to occur, please go back through these same 11 steps but when performing step 8 additionally check the box entitled "Replace permission entries on all child objects with entries shown here that apply to child objects" and be sure to reboot in step 10.
