I have a Surface Pro 4 (Win10) with Acrobat DC v21.0 running. I also have Acrobat Reader v2001.001.20145 in case I am signed out of CC on the road and want to read a pdf quickly (without going through the sign-in procedure). I have had this configuration for several years.
I have started to get sporadic warnings of multiple instances of Acrobat Distiller running over the last couple of months. Below is an image.
The Control Panel verifies only DC and Reader are running. Has anyone seen this before and can anyone advise how I can troubleshoot to stop this? Any help would be welcome.
Hope you are doing well and sorry for the trouble. As described you are getting the error 'Another instance of distiller is busy starting up. This instance can not continue'
Please look at the correct answer marked in a similar discussion https://community.adobe.com/t5/acrobat/another-instance-of-distiller-is-busy-starting-up/td-p/101255... and see if that works for you.
Hope it will help
Many thanks, Amal. I will do that next time. But I think using Task Manager only stops additional instances that have started running, not solved additional instances from ever starting.
Distiller is a part of Acrobat (not included with Reader). I'm not sure what control panel you mean, can you give more details about how you are checking what is running please?
I am talking about the Windows Control Panel.
Yes, which Windows control panel please? There are many... but I can't think of any that do this.
There is only one Control Panel, but it has lots of sections😊. I'm talking about where it lists out the programmes. There is only DC and Reader listed. Additionally, Task Manager lists only one version of DC running.
The Programs control panel shows you only the programs you have got installed. It doesn't say anything about whether they are running. And where a Program includes other programs it doesn't show anything at all. Task manager shows what is actually running. Distiller will show up, if it is running, as "Acrodist".
The big question is, I guess, are you actually trying to use Distiller, or it just randomly starting? Distiller is almost entirely used when you print to the Adobe PDF printer - it runs behind the scenes to make that work.
