Hello,
So basically i installed ASCEMU2 v1.1.0 first, then i installed Arturia VC 9 v5.2. (VST2, because for some reasom ableton couldn't find VST3 that i first time tried to install)
Disabled windows defender and other security options. Run Ableton as administrator.
I open Ableton and take the plug ins one by one to check if they are activated, the first 1-2 i pick randomly seem to work, and after i pick another one, it opens with the Authorization screen on and Demo warning message. I close Ableton, re open it, same thing happens.

PS: I also made the ASCEMU2 folder as an exception in windows defender.

I don't know what to do, i have uninstalled the plugin pack, deleted all the remaining files, then reinstalled it, same problem. I even tried to block the arturia in the host registry or open Ableton while offline, thinking it might trick the authorization login screen, but it didn't work.


Any ideea what i could do to solve this?

 

do the standalone arturia instruments run? things like Piano etc?
How about Analog lab? does it run?

download reaper and see if it recognizes the vsts

you need to troubleshoot your system, by testing
