I just tried to update my 6700 to SSDR 2.3.7. I launched the new software on my W10 PC and turned on the 6700 (power cycle before update). The software detected the need to update and I clicked Update. The update process proceeded, I noticed messages on the 6700. The Update progress bar completed, but nothing else happened. After several minutes, following a note in the release notes, I powered down the 6700. It shut down with just a press of the power button. I restarted the 6700, the SSDR screen which was still showing did not change. I shut down SSDR and restarted. It detected that an update was required. I clicked Update. It went through the whole update process and again hung with the progress bar complete. I let it sit for about 15 minutes. No change. I powered down the 6700, removed DC power for 15 seconds and started it up again. The process still did not complete. I started up my Maestro and it connected to the 6700 using version 2.2.8.
