Rainmeter Plugin Cannot Connect to Hwinfo

Hello, this looked like the right place to post about my issue. I want to use hwinfo to set up a rainmeter skin on my new installation of Windows 10 (because they removed gadgets :mad: ) and for some reason the plugin is not able to see that hwinfo is running.

Here is the specific error I get in the rainmeter log: 

"ERRO (00:00:00.078) : HWiNFO.dll: Could not connect to HWiNFO.  Please ensure HWiNFO is running, sensors are active, and shared memory is enabled."

When I try to run the memory viewer I get a similar error that says that it could not connect to hwinfo: 

I have shared memory active, Hwinfo is running the dock, and I believe that sensors are running? (not sure how to check that)

Im not sure what is wrong but it could have something to do with Windows 10? I am running Windows 10 Pro Insider Preview Build 10166. Intel i5 3570K, 16GB Corsair Vengeance 1600mhz, Nvidia GeForce GTX 970, Primary Drive: SSD 120GB, Secondary Drive: HDD 1TB.

Rainmeter version is: 3.2.1 r2386 64-Bit
Hwinfo plugin version:

I don't think this is related to Windows 10, I have just tested it there and no issues.
Does the HWiNFOSharedMemoryViewer report values ?

Which version of HWiNFO are you using? Is the HWiNFO sensors screen active?
My HWiNFO version is v4.64-2530 and as far as I can tell, the sensors are active. They report values and I have it set to update on a 1s interval.
Ok, I actually found my issue because of what you asked! I had no idea that the program didnt report sensor data when the sensor screen was not open, which is why it was saying I was not connected. I have it set up so that the sensors are always active in the dock now. Thank you for your help!

I see this is a very old post. would you mind telling me what you did to fix your issue? Thanks.
Open HWInfo Settings (in top right, Program > Settings).
Enable 'Show Sensors on Startup', 'Minimize Sensors on Startup', and 'Minimize Sensors instead of closing'.
Reload HWiNFOSharedMemoryViewer and it should be reporting values now.
