Folding Forum

Hi.
thanks to the recent drop in price, I upgraded my Pc / win 10 and my kid pcs changing some very old Gpu with an 1660super and a 3060ti.

Both Pcs were running FAH . Before....

I removed FAH via control panel,the the AMD driver using DDU and I installed Nvidia Driver and the I tried to install the new version 7.6.21.86

I install it but it seem that the FAH client, for some reason doesn't automatically start at boot.

Weird
I went to the fah folder under programx86 folder and I double click on it
It recognize the cpu (ryzen 2800x) and the GPU 1660 super
it start loading the work but it stop and give me this error:

15:24:56:ERROR:WU00:FS00:Exception: Failed to open 'cores/cores.foldingathome.org/win/64bit-avx2-256/a8-0.0.12/Core_a8.fah/FahCore_a8.exe': Failed to open 'cores/cores.foldingathome.org/win/64bit-avx2-256/a8-0.0.12/Core_a8.fah/FahCore_a8.exe': Accesso negato.

The same thing happen with the pc with 5950x and rtx 3060ti
but it failed with a smilar error( but ...avx2.exe file

What can I do ?
I can try anything besides reinstalling windows as I have a professional Cad software that make me real troubles to activate and cost a fortune and I need for work.

I am 100 % positive that the removal was not complete. When launching FAH client manually it look in some database.... and it configure my CPU slot with 14 cores ( instead of the real 16) and 22 (instead of 24) that was my previous configuration (n-2) cores

Any suggestion welcome

My guess would be that your internet security application is interfering.
Sometimes the folding at home software can be falsely flagged as malicious/malware.
Your internets security application should have an exceptions list (a list of folders/files/processes which you can tell it to ignore).
Add the following folder locations to it:-
*). C:\ProgramData\FAHClient
*). C:\Program Files (x86)\FAHClient
