[Guest]

Hello!
Use OS Windows server X64 2008 r2 EE english
I have motherboard Gigabyte GA-EP45-DS3
and many years use Alcohol 120% - yersterday i update Alcohol 120% to 2.0.1 Build 2033 It includes sptd 1.74

Now any programs Alcohol or Daemon tools cannot create virtual disks and send error

Alcohol send Unable to add adapte - invalid user buffer
Daemon send - cannot add virtual disk

100% problem it SPTD 1.74
Then i use previus version of Alcohol and SPTD 1.54 (may be i wrong)
It works on SERVER 2008 R2 PERFECT!! but after update to 1.74 all BAD!

I try to downgrade to 1.54 but nothing change...

I clean regedit - reinstall SPTD and ALCOHOL but problem still here! =(
What can interfere to create virtual disks in this programms?

PLEASE HELP!!!

We will investigate the issue, Hyper-V should be no problem.
