The case of the missing dotXSI.dll (NT) or (IRIX)

A customer reported that he couldn’t import or export dotXSI, and that he got this message in the history log:

# INFO : 4011 - Import/Export .xsi: The dotXSI.dll (NT) or (IRIX) is missing or the class is not registered.

From past experience I was pretty sure this was a PATH problem, but just in case I also suggested running runonce.bat to make sure everything was registered:

  • Check that “C:\Program Files\Common Files\Softimage” is included in your system PATH environment variable.
  • In a Softimage command prompt, run runonce.bat, to make sure all DLLs are registered.

It turns out the problem was indeed the PATH environment variable: it was missing C:\Program Files\Common Files\Softimage.

To check the PATH, click Start and open the Control Panel. In the Control Panel window, type “environment” in the Search box, and then click Edit the system environment variables

The case of Error 1603 and the corrupt PIT file

In a recent case, a customer reported error 1603” during installation. As I’ve mentioned many times in various places, error 1603 is a generic error code that doesn’t tell us much. So, you can either apply some generic troubleshooting (reboot, check download, disable UAC, reinstall VC++ manually, …) or check the detailed installation logs for more specific information.

The problem is this specific case was that the installer wasn’t able to update ProductInformation.pit. Without looking at the logs, I don’t know whether you would ever figure this out.
