GMiner has a "feature" where it tries to detect tampering. When you launch Gminer from other applications it can on some systems trigger this tamper protection.
It's unfortunately nothing I can do from an Awesome Miner to resolve this as it's a Gminer behavior. What you could try is to run a little older version of Gminer to see if that works better. You can configure this via the Options dialog, Managed Software section.
Older versions of GMiner don't work either, it's not the GMiner that changes version-to-version, it's Awesome Miner. I already posted this issue here before, and the very next release of Awesome Miner fixed the issue, so I assumed that I was heard and the issue was dealt with, and everything worked fine for several updates more, but now GMiner doesn't work again, any version of it. I asked the developer of GMiner too, and was answered that it's not their fault and they cannot deal with every miner management program that launches their miner.
Please start Gminer with the Diagnostics button in Awesome Miner and share the output with me.
If it's the "anti-hacking" error message from Gminer I will contact them and see what it's about. It looks like it appears at random, although it works fine for almost all other users. There is nothing I can do from an Awesome Miner point of view here as it's Gminer behavior.
If you have any replies or discussions with the Gminer developer already, please forward it to me via PM. Thanks!
