I have a watir test that downloads some information from a web app to an Excel file, and I then open the file to confirm the contents. On my dev box everything works fine, but the scheduled automation runs (via Hudson) always fail attempting to open the Excel file. I have checked that the correct version of AutoITX3.dll is registered on both machines (Ruby 1.8, Watir 1.6.5). No other versions of AutoITx3 are registered on either machine. The error on the Hudson box is the one expected if the dll is NOT registered, but it is present in regedit in the same location as on my dev box. Both machines are WinXP.
Running the test manually on the Hudson box results in the same error — unknown OLE server: ‘Excel.Application’ HRESULT error code:0x800401f3 Invalid class string.
I searched for similar errors and saw one instance where running on a virtual machine had caused similar problems, but only if the VM window was closed. I don’t think this is a code error since it runs on the dev box. Any suggestions for debugging this?
TIA,
Sabrina
I finally figured it out. What I thought was a working Excel install on the remote machine was instead the free Excel reader, which does not have the API hooks WIN32OLE looks for in the registry. Installed the full Excel program and now everything works. I knew the Universe would be consistent!
