Hi, i used Command Center to download and install Dimention Pro and when installing, it just sais "installing" forever and never installs it. I then quit command center and reopen it, and it shows a grean light in front of the Dimention Pro item. When I open Sonar, Dimention pro does not appear in the synths list... The Dimention pro folders seem to be at the right places in the Vst Folder etc... I then ask Command center to reinstall Dimention pro, and the same thing happens.. Could it be that the downloaded file is curruped? How do I force Command center to RE-DOWNLOAD Dimention pro? Thank you for any answers.

Update:
I found the downlad path of command center (well hidden) and delited the D-Pro file. I reinstalled D-Pro from the command Center menue. As predicted, it downloaded again the D-Pro file and installed it. D-Pro installed all its sound banks etc, but at the last stage of installation, the install program cant seem to finish installing.. I am looking at the command center screen and i see: "Installing D-Pro" and an orange bar is moving left to right... It's been like this for the last 15 minutes... Yesterday i let it run all day while I was at work.. cameback home and Command Center still was "Installing D-Pro"
Any suggestions?

A long shot, but make sure you have plenty of free space left on your C: drive.  You can get all kinds of weird behavior as you near the last 10% of space on your system drive.  Also, you might try temporarily disabling your antivirus during the install.
 
If you know how, check your system logs for any errors. 
 
Alternatively, you could always do a manual install.  I've always done this for Dim Pro and Melodyne (Out of old habits, I guess).
 
You can find the installer file(s) under "My Products" in your CW account.

thanks for the tip!. By the way I have windows 10 (I had Window 7 before and it worked like a charm... ) I hate microsoft so much... I tried downloading D-pro from "My products" as you said but stupid windows 10 interupted the download with a massage saying someting like "We interrupted this download to protect your computer" WTF!?!?! F**K You Windows 10

Try disabling antivirus during install.

Perhaps you have an update pending in Windows 10. Go to Windows - Power and see if it says there is an update.
