	New installation. I'm seeing if I can migrate from using VSCode and PlatformIO to VisualMicro. Using the Raspberry PI Pico. I wrote a simple blink program to test end to end, and I'm having trouble uploading to the Pico. I have a valid COM port and I'm choosing the PICOTOOL for the Upload Method. I'm choosing that because (at least with PlatformIO), I do not have to put the pico into boolsel mode. The Picotool upload fails with a general error message: "The uploader returned an error" In looking at the command for the upload, I get the following: Uploading 'VisualMicro Pico Test' to 'Raspberry Pi Pico(rp2040_rpipico)' using 'COM10' Uploader started for board Raspberry Pi Pico(rp2040_rpipico) Upload method will be: bootloader Uploading via Bootloader 0-a-d3d2e6b\picotool load "C:\Users\rareddy\AppData\Local\Temp\VMBuilds\VisualMicro Pico Test\rp2040_rpipico\Debug/VisualMicro Pico Test.ino.uf2" -f The uploader returned an error When I enter into a command window and attempt to run this, I get a windows system error dialog: "The code execution cannot proceed because libstdc++-6.dll was not found" I click OK and I get the same message but for file: libgcc_s_dw2-1.dll I messed around for hours last night trying to fix this. I was going to try to build my own version of picotool but that required libusb and after screwing around trying to get that installed and found when building, I gave up. I'd much rather have a one-click solution than having to install my own toolchain anyway, since I will need to do this on a 2nd machine. Any help?

	Thanks for the report. The DLL errors are caused by the tools included with the board package being incomplete, or having a dependency which is not automatically installed. One route is to ensure you have the MinGW64 DLL files available on your machine, and these are all included in the GitSDK tool for windows. You can just clone their GitHub Repo for the files, or use their installer to setup Git fully. Once installed you will be able to find the GitInstallFolder\mingw64\bin folder, and adding this to your Systems' PATH variable will then allow the PicoTool to work correctly. We will check if this has been raised with the tool and package creator as it will be problematic for a wide range of users.

	Unfortunately adding that folder into the system path didn't fix the problem. Note that the git\mingw64\bin folder doesn't contain the DLLs which are missing that picotool is looking for. Can someone try this and see how it works on their system?
