Create ComWrapper error

[Huy Nguyen 2]

We are trying to launch Spotfire Analyst from our application by creatinga Spotfire ComWrapper as follow

new ComWrapper(Activator.CreateInstance(Type.GetTypeFromProgID("Spotfire.Dxp"))

and got the error

Exception: {"ClassName":"System.IO.FileNotFoundException","Message":"Retrieving the COM class factory for component with CLSID {8B9A5DE9-DEB8-11DB-97F1-0011D8B1A5F4} failed due to the following error: 8007007b The filename, directory name, or volume label syntax is incorrect.

We already check Spotfire Analyst 7.12 working correctly

Registry value atComputerHKEY_LOCAL_MACHINESOFTWAREClassesCLSID{8b9a5de9-deb8-11db-97f1-0011d8b1a5f4}LocalServer32 is correctly pointed to the right exe

This only happens on 1 of our test machines, all other machines dont have the issue

How can we fix this

Thanks

Hello,

The error0x8007007Boccurs when the system is set to store restore points to a wrong path or location.

In your case looks like its not able to find the "Spotfire.Dxp" application.

Since the issue is specific to a machine you can re-install the Analyst client and see if that makes any difference.

We did reinstall Analyst and that didn't fix the problem
