New B745 Cant Install Dragon Center...please help

First Comment
edited November 2023 in PowerSpec
Hi, I've read several message boards about this subject but still struggling.  My new B745  (purchased 12/28) has a Z490 motherboard.  Tried to download Dragon Center from the Z490 site and the link is blank for the recommended version.  When I download from MSI, the program fails to install saying it is blocked by firewall or antivirus.  I've gone in and given program permission to bypass the firewall--still no luck.  Very frustrated because I cannot control the computer's RGB lights without Dragon Center.  Mystic Lights will not install seperately.  Please advise.

    I fixed it.  MSI has a uninstall tool for Dragon Center 2.  Run the tool and delete SDK.  Then reinstall Dragon Center.  Windows Update has an SDK already installed that interferes with install of Dragon Center.

    You're a genius! Took me so long to troubleshoot other solutions and this one worked perfectly. Thanks!

    Can you provide a link to the uninstall tool?  And for the correct Dragon Center package?

    Looks like the tool is on the MSI forums:

    Here's another way that should help you work around it and install Dragon Center on this board. This is meant to be used on our Powerspec system, with a previous standalone Mystic Light install.

    1. Copy the contents in the quote box below into notepad. Save, change the file type to "All Files". Name the file to <name>.bat. The name doesn't matter, I called mine MSIUninstall.bat.

    2. Right click on your new batch file and "Run as Administrator". Shouldn't take more than 10-20 seconds to run. The command prompt will close when it's done.

    3. Open the start menu, right click on Dragon Center and "Run as administrator" as you're originally instructed to do. Should install the MSI SDK correctly this time, after a few minutes and run normally. No restart required.
