Seeing how I just lost my Rational Tools, I decided against that. I did have one other virtual desktop that had the right version of the Rational Tool Suite. With the two virtual desktops, I am still able to do my job.
The plan from my manager was to get a new virtual desktop with all the software installed. A member of the customer organization was to get me the new desktop. Well eventually I got it. But nobody was scheduled to install all the software. Eventually somebody called to see if the trouble ticket to get my new desktop could be closed. No way. I don't have a working machine. Now my team lead has to sort through this mess. Oh boy.
