SiAppDll load failing

Hi,

I am trying to run the SDK examples and I am getting a message that the SiAppDll dll is failing to load.

I am using a SpaceBall 5000 USB.

When I run the app through Visual Studio in debug mode, I have found that the __SiAppInitialize fails when trying to get the address of the fnSiSyncSendQuery function. Can someone help point me to why this might be occuring?

Thanks,
Nick

I think you have an old version of siappdll.dll. Delete it from system32 and reinstall the 3Dx software. Delete spwini.dll also while you are at it, before reinstalling.

Hi,

Thanks for that.

Had to manually remove dlls as you suggested - installing over the top did not work for some reason.

All working well now.

Thanks,
Nick

The MSI installer won't install over DLLs that have usage counts that indicate that they are in use, or if the versions aren't greater. That's why you had to delete them manually.
