ALM C# application

Question

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?

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.

Answer 2

It's necesary to download the TDConnect.exe

1. Go to your HP ALM web interface
2. 'Tool' link
3. 'HP ALM Connectivity' link
4. Click on 'Download HP ALM Connectivity'

it will download TDConnect.exe file, you need to do this trhu your instance to match the TDConnect.exe with your version, for example if you are running HP ALM 11.52 you MUST download the TDConnect.exe for this version.
