Environment:
Win 10 Pro x64
Visual Studio 2019 16.8.6

The issue happens all the time. I've also tried running VS as an administrator but with same effect.
I've also noticed that plugin settings are lost everytime after I restart VS.

Apparently restarting the computer after the plugin is installed does make the dump succeed.

>dumpmem -f d:\Temp\sample.raw mImageData mSize.X * mSize.Y * 4
Wrote: 2240000 bytes to: <file://d:\Temp\sample.raw>.

however the settings are still lost after each restart of VS.

Hi,

for memdump error, latest build on github releases page 3.4.0.0 changes the way memory is read / written. This should fix the occasional access denied error.
