REW 5.14 and higher freezes on start

[benrumsey]

I cannot get rew 5.14 - 5.20rc14 to run, both 32 bit and 64 bit. It loads and then immediately freezes. When I hold the mouse over the close button it just blinks and I have to kill it with task manager. rew 5.13 works fine. I am running avast and have tried disabling it with no affect. I have also tried reinstalling java 8 32 bit and 64 bit. I also have vmware workstation installed, not sure if other vm software can interfere. I don't see a log file, unless I am looking in the wrong place.

Nothing helpful in the log file that I can see.

No, no clues there. Could try running the installer with hardware graphics acceleration deselected to see if that makes any difference.

 

[benrumsey]

reinstalled with no graphics acceleration and 512mb memory limit, no difference. with a fresh install the help window comes up automatically and is also frozen. I don't know what the difference between 5.13 and 5.14 is that would make it not run. I didn't see anything major in the change log for 5.14.

Perhaps there is some issue with the Java runtime on AMD Ryzen, I found another comment about REW not running on "Threadripper 16 cores".

 

[benrumsey]

I will do some experimenting and try to get more information. I thought only early ryzen had virtualization issues. maybe I will try running it inside a vm.

 

[benrumsey]

It ran inside a vmware windows 10 pro vm running in windows 10 without an issue. Not sure what to make of that, any ideas?

 

[John Mulcahy]

I'd still think it is a processor-related issue.

 

[benrumsey]

After some exhaustive testing I found the issue. I have a cronus max game controller adapter, unplugging that device fixed all of my issues.

 

[John Mulcahy]

Good job figuring that out. Why it caused a problem I have no idea. Some software that alters the way the OS UI operates can cause issues, not sure if the adapter falls into that category.
