Update: Did the install again but this time when it asked if I wanted to install in "DXLabLauncher" (which is strange in itself) I changed it to "DXLab" and checked "yes" when asked if I wanted that folder created. Lo and behold all of the installions were installed! However, Commander, Spotcollector, etc. are NOT in the "C:\\DXLab" directory. They were all instead installed in the "C:\\" in spite of my instructions. The only thing in the "C:\\DXLab" is Launcher and some other stuff like Launch Agent. I just check Launcher and there were some upgrades which installed with no problems.
Anyway, I'm taking a break but will see if things actually work later. I still have not idea why all of this is happening. It's really weird!
