i tried many bat files.

The current one:
setx GPU_FORCE_64BIT_PTR 0

setx GPU_MAX_HEAP_SIZE 100

setx GPU_USE_SYNC_OBJECTS 1

setx GPU_MAX_ALLOC_PERCENT 100

E:\miners\lbminer\gpu\sgminer.exe --kernel lbry -o stratum+tcp://lbry.suprnova.cc:6256 -u minerjoen.gpu -p 1 -I 19 -w 64 --gpu-threads 2

i use the complete path, i also see he start the sgminer.exe and close directly
i also tried just sgminer.exe instead of complete path
i also tried without the -I, -w, gpu threads
i also tried -kernel instead of --kernel

I tried with and without antivirus
i tried with catalyst 15.x and 16.x
Got net framwork (last version)
got amd sdk (last version)
Got windows 10 pro 64 bit full updated
i tried on ubuntu (Same shit)

All other coins works fine, also the sgminers.. i also tried to place a other sgminer to the lbry miner, not working (while the same sgminer works on other coins in a other folder)

i tried the complete zipped working folder from Lafu, the one he is using now.

Also if u look at the internet, many people got this same issue.

I mined many, many coins in the last 4-5 years.. This is the FIRST time a miner is not working (ethereum was strange to start but no problem), if i run a random x11 miner of scrypt of sha or ether, all work directly. its only this coin-miner.
