Iam having an issue with the Lulzbot and Ultimaker Cura only allowing one of the versions to run at a time. Iam trying to run both the Luzbot and Ultimaker Version of Cura at the same time because I have both a Taz 6 and a UM3. Is anyone else having this issue?

Update

UM3 Cura loads splash screen but does not complete/Run. I can get the Lulzbot/Cura version to run.

These versions are not getting along on the same computer, which is running Win7.
