Cgminer won't run on Windows 8.1

krasticrypto

I freshly installed 8.1 and cgminer won’t work…any clue? it opens but then closes straight away.
I tried these:
disable Windows Firewall
put the whole cgminer folder on Programs 86x
run cgminer as administrator…
but no luck!!!
…grrr…

I’ve got Windows 8.1 on my 7 rigs and it runs fine…

Is it popping up and disappearing straight away? What’s happening?

Also, you might want to try SGMiner, it’s a bug fix for CGMiner 3.7.2…

krasticrypto

yes it opens but only shows that cgminer line and nothing else, it closes again right away…
there is no antivirus and my account is admin…
I’ll check out that sgminer now, haven’t heard about it before…

It means there is a syntax problem with the arguments you are passing in your .bat file, post you’re settings mate…

try to just go to cmdline and start it with cgminer --benchmark,
just to check it will run.

Im betting you have an small error in you startup file, something really easy to miss. for example forgot to specify port number on pool, missing an - or something.

sorry for the delay,been busy…

so: I was under the impression that cgminer should run even without a .bat file, as you could insert url of pool etc once cgminer starts,anyway…

now I created a bat file like this but still doesn’t run.

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://stratum.wemineftc.com:4444 -u krasticrypto.1 -p xxx -i 13 -g 2 -w 256 --thread-concurrency 8192

svennand: I’m probably doing something wrong but I would like to do the test you recommend, helpme please I’m not that good with cmd and stuff…:

I press Start+R to open the cmd line, I type in cgminer --benchmark and error message says it can’t find the archive of cgminer… where should cgminer be for this work? in Windows/programs 86x?

I re-installed Win 8.1 from scratch and it works…very odd…

1 thing I learned from this:

after installing Win 8.1 and running all the updates apparently this is enough to have the appropriate drivers for the GPUs, no need to download and install AMD Catalyst.

so someone says in other forums and seems correct…maybe installing AMD Catalyst cons=fused things? …mmm…anyway thanks for hte help…
