Symptoms
Getting an error when installing K2 for Visual Studio 2013 onto a 32-bit client machine.
Diagnoses
If you look at the log files, it appears as if setup manager is looking for the MS VS install directory in the "Wow6432Node". Seeing as this node does not exist on a 32bit machine, the installation fails.
Resolution
This is a issue in 4.6.8 and LABS are aware of it. If you run into this issue, log a ticket and K2 support will provide you with a cold-fix.
