If you don't use the SisiLauncher (either you manually patch to connect to Singularity, or don't connect to it at all) you can ignore this.
When attempting to run the latest SisiLauncher
on Linux (Ubuntu 10.10 64-bit, wine 1.3.13) it failed to run with the following:
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.
I had already installed "vcrun2005" through Winetricks but this wasn't enough.
This version of SisiLauncher uses the vcrun2008 libraries.
Installing that via "winetricks vcrun2008" solved this problem.
