There are a few things we can do to fix this issue, any one of these could resolve the issue on your rig
- Check “Secure Boot” is set to disable in your BIOS – Not all BIOS support this so you may not even have this option

- Upgrade XMRig to latest version
How to set “Run As Administrator” on NiceHash Application Shortcut
You can start of with the easy single use one click “Run As Administrator” like this. Right click your NiceHash Short cut and select “Run As Administrator”. This will run the App as Admin but just this once. Next time it will run as a normal user unless you repeat this step
Or you can try a more permanent solution and tick the option under the properties of the short cut to apply every time the app is launched
Right clicking > Properties > Compatibility tab > Tick “Run this program as an administrator”
Next (people always laugh at this but it’s for good reasons) Reboot your rig and try running the miner again, if you still have the error, proceed to the next steps.
How to set “Run As Administrator” on NiceHash Application
For this you will need to navigate using File Explorer and find “NiceHashMiner.exe” default is located under your user profile and so will be different too my rig.
“C:\Users\<your login user name>\AppData\Local\Programs\NiceHash Miner\NiceHashMiner.exe”
On finding the location check this is also set to “Run this program as an Administrator” It may have inherited the permissions from your shortcut but its best to check
Next, reboot the mining rig again. If you still have the error, try next step
How to set “Run As Administrator” On the actual XMRig Miner
This one can be a little trickier to find as NiceHash Miner uses some odd folder names.
Open Task manager > Find and expand “XMRig miner” > Right click on “XMRig X.XX.X” > Open File Location
Now Right Click on “xmrig” and Select > Properties > Compatibility tab > Tick “Run this program as an administrator”
