How to fix the error for the interop when you dont have microsoft office installed

I have this code on my service:
Application xlsApp = new Application();
xlsApp.Visible = false;
Workbook wb = xlsApp.Workbooks.Open(dictionaryPath);
Sheets sheets = wb.Worksheets;
Worksheet ws = (Worksheet)sheets.get_Item(1);
var numberOfRows = ws.UsedRange.Columns["A"].Rows.Count;
var firstCol = ws.Range[dictionaryColumn + "1:" + dictionaryColumn + numberOfRows];
values = firstCol.Value as Array;
And when I run because I don't have Microsoft Office installed on my server I get this error:
System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

And I know that one of the solutions is to install the Microsoft Office but I am not allowed to do that so is there any other way to access the excel and not to install Microsoft Office. I use COM Interop and it is included in the project I also tried installing Open XML SDK 2.5 but for some reasons it didn't work. Can some one help me find a solution

App work in console, not as windows service

I have an app using COM library. When i run it to test in console app it works good. But when i install it as Windows Service using installutil. In logs i have error

Anyone have idea, how to solve it?

One of the common problems in this scenario are user permissions, because the service runs as a different user than that who runs in console. But judging by the comments on the question, you already checked it.
Another source of errors is the fact that the working directory of the console application is the directory where the EXE is located. With Windows Services, it's not; the working directory is C:\Windows\System32 (or wherever %SYSTEMDIR% is). So, if you have code that relies on the current working directory (such as reading a file in the same directory), it will not work as a service. I'm not sure, but maybe the same problem could happen if you are trying to load a COM library in the same path as the EXE.
So, what I suggest you:
Double check your permissions.
Check any code that relies on relative paths and change it to absolute paths instead.

Configuring Fluent NHibernate with System.Data.OracleClient

I'm trying to use System.Data.OracleClient instead of Oracle.DataAccess with Fluent Nhibernate . From what I understand, in order to achieve this I should change my driver from OracleDataClientDriver to OracleClientDriver. I've configured it like below, but I get an error that looks like it is still trying to use OracleDataClientDriver. What am I doing wrong?
FluentConfiguration configuration = Fluently.Configure()
.Database(
OracleDataClientConfiguration.Oracle10
.ConnectionString(x => x.FromConnectionStringWithKey(connString))
.Provider<NHibernate.Connection.DriverConnectionProvider>()
.Driver<NHibernate.Driver.OracleClientDriver>()
)
Here is the error, it is still looking for Oracle.DataAccess which I'm trying to get away from.

Use OracleClientConfiguration and OracleClientDriver instead of OracleDataClientConfiguration and OracleDataClientDriver
FluentConfiguration configuration = Fluently.Configure()
.Database(
OracleClientConfiguration.Oracle10
.ConnectionString(x => x.FromConnectionStringWithKey(connString))
.Provider<NHibernate.Connection.DriverConnectionProvider>()
.Driver<NHibernate.Driver.OracleClientDriver>()
)
The comments in the question solved my problem. I've posted this answer for the benefit of others, #PapaBurgundy & #Rivarolle deserve full credit for the answer.

How do I clone a OLE/COM registry entry for use with different settings

I have written a C# program that is to interface with Catia v5.18 via OLE/COM. It is going to be a common case where the machine the program is ran on will have multiple versions of Catia installed on it. Both older and newer and installed in any funky order. The last one installed gets to put its settings in the registry.
I'm trying to setup the registry to use a new handle to connect only to a 5.18 CNEXT server. I found the Catia.Application entry in HKEY_CLASSES_ROOT and the CLSID entry. I made copies of these and provided a new UUID for CLSID and came up with the following registry import file:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\CATIA.Application.v518]
#="OLE CATIA.Application"
[HKEY_CLASSES_ROOT\CATIA.Application.v518\CLSID]
#="{ba3ca493-05fb-4188-a767-f40c03db2672}"
[HKEY_CLASSES_ROOT\CLSID\{ba3ca493-05fb-4188-a767-f40c03db2672}]
#="OLE CATIA.Application" "AppID"="{ba3ca493-05fb-4188-a767-f40c03db2672}"
[HKEY_CLASSES_ROOT\CLSID\{ba3ca493-05fb-4188-a767-f40c03db2672}\LocalServer32]
#="\"C:\\Program Files\\Dassault Systemes\\B18\\intel_a\\code\\bin\\CNEXT.exe\" -env \"CATIA_PLM_Express.V5R18.B18\" -direnv \"C:\\Documents and Settings\\All Users\\Application Data\\DassaultSystemes\\CATEnv\""
[HKEY_CLASSES_ROOT\CLSID\{ba3ca493-05fb-4188-a767-f40c03db2672}\ProgID]
#="CATIA.Application.v518"
[HKEY_CLASSES_ROOT\CLSID\{ba3ca493-05fb-4188-a767-f40c03db2672}\VersionIndependentProgID]
#="CATIA.Application"
I verified that the import worked, but when I run my application I come accross the following error when I try to connect to it.
System.Runtime.InteropServices.C OMException (0x80080005): Retrieving the COM class factory for component with CLSID {BA3CA493-05FB-4 188-A767-F40C03DB2672} failed due to the following error: 80080005 Server execution failed (Exceptio n from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean skipCheckThis, Boolean fillCache)
at System.Activator.CreateInstance(Type type, Boolean nonPublic)
I'm able to run this program fine on the normal installs using "CATIA.Application" and "CATIA.Application.1", but here is the code I use to connect to the Application if it matters:
public CatiaApplication() {
Type catia_program_id = Type.GetTypeFromProgID( "CATIA.Application.v518" );
try {
this._instance = (Application)Activator.CreateInstance( catia_program_id );
}
catch( Exception ex ) {
throw new ApplicationException( "Failed to access Catia Application: " + ex.ToString());
}
}
Anybody have any ideas? I haven't tried to reboot the box but so far it looks like the changes take effect immediately.

Shouldn't it be this instead?
[HKEY_CLASSES_ROOT\CATIA.Application.v518]
"CLSID"="{ba3ca493-05fb-4188-a767-f40c03db2672}"
where you wrote it:
[HKEY_CLASSES_ROOT\CATIA.Application.v518\CLSID]
#="{ba3ca493-05fb-4188-a767-f40c03db2672}"
