When tried to connect to Harvest broker from Visual Studio/VS 2022 via Harvest plug-in we got this error
Retrieving the COM class factory for component with CLSID {6EB5D243-66A5-11D2-9061-000064657374} failed due to the following error: 800700c1 is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
CA Harvest Software Change Manager 14.5.01, Visual Studio 2022 plug-in
If the Harvest client on the VS 2022 machine has version level below 14.5.01, this error occurs.
Make sure your Harvest client on the Visual Studio machine has the same version level as the Harvest broker server.
For example, if your Harvest broker server has version 14.5.01 but on the VS machine you have Harvest client 14.5, you will see this error.
Once the client version is confirmed not matched the broker server version, you will need to upgrade the Harvest client to the same version level as the broker server and then try again.
Note: if the client version is the same as the broker server version and you still see this error, please contact Broadcom Support.
