ALM C# application

I am using Interop.TDAPIOLELib dll to connect to ALM (application lifecycle managment).

In order to connect to the project i am using TDConnection but when executing this line

 _connection = new TDAPIOLELib.TDConnection();

i get this exception

Retrieving the COM class factory for component with CLSID {C5CBD7B2-490C-45F5-8C40-B8C3D108E6D7} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

This code was working fine before i repaired my HD

I run sfc/scannow and i got this message Windows Resource Protection did not find any integrity violations. Which indicate that i do not have any missing or corrupted system files.

any suggestions?

Solution

OTAClient.dll should be registered using regsvr32.exe register the OTAClient.dll it located in this path C:\Program Files (x86)\Common Files\Mercury Interactive\TDAPIClient and make sure that the application is run under x86 target.
