Comm Error observed while using ALMTaskforBambooPlugin

[Former user]

HI ,

We are using ALM Task for Bamboo plugin to integrate Bamboo with ALM. While using this plugin following error is observed :

ALM Test Execution Failure|Verify execution failures|0|FAIL|Unable to cast COM object of type 'System.__ComObject' to interface type 'TDAPIOLELib.TDConnection'. This operation failed because the QueryInterface call on the COM component for the interface with IID ' {62D83266-71EF-4F8B-8AE6-661D614D0769} ' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

We tried following in order to resolve this issue. • Changed COM/DCOM settings in machine where we want to run • Placed msenv100p.dll here : C:\Program Files (x86)\Common Files\microsoft shared\MSEnv then used following commands regsvr32 /u msenv100p.dll regsvr32 msenv100p.dll • Installed Remote Addins for ALM

Can I get detailed understanding what exactly is going wrong.Also, can I get a basic requirement for running this application on Windows.

We are high priority to deliver a product which requires this, and currently we are blocked. Can you help us ASAP.

PS : Checked with ALM as well as Windows team there conclusion is something to do with Plugin itself.

When you get error message like "No such interface supported", usually it means your QC/ALM client doesn't register correctly. Need to do it again.

1. Add in site administrator, Site configuration Tab the parameter DISABLE_COMMAND_INTERFACE and set it to "N".

"If this parameter is set to "Y" (default), only users be longing to the TDAdmin group can use the OTA Command object. If it is set to "N", any user can use it.If it is set to "ALL", no users can use it. For more information, refer to the HP Quality Center Open Test Architecture API Reference."

2. Open ALM-> Tools  -> Help -> Open Add-In Page -> Install TDConnect (for connectivity) would resolve the issue. It worked for few users.
