REW does not start on windows 10

Hi

REW does not start, it displays first screen with initializing on the bottom for 2s and then it closes.
Can You help me?
My interface is focusrite 8i6
System is windows 10

I never used it before it is my first run.
i downloaded this version:
Windows installer with JRE allowing multiple instances (30.5MB)

Attached my log file
Seems to be some java problem


Thanks for the help

You don't mention which version of REW you were trying, if you haven't already tried the latest beta version from the Downloads section please try that. From V5.19 beta 5 a workaround was added to address a Java incompatibility with the Windows 10 Creators Update.

I pasted a link, my version is: 5.18
I'll try the beta, Thanks.

As a first time user, I have a similar problem with V5.31.3, 25th July 2024, on windows 11 (current on updates), with previous java versions removed prior to pristine install.
REW does not start. No splash screen or anything visible. In the new_output.txt I find:

The roomeq_wizard0.log is empty. There are no other files in the directory holding new_output.txt.

I found several similar reports on previous builds over the years, and tried some of the suggested fixes (uninstall, reinstall, reading the welcome.html but could not find anything to help this specific situation).

I hope there is a way to overcome this as I found the use of REW on a friend´s laptop very helpful.

You could try the 5.40 beta build to see if that behaves any differently. The underlying problem is with the way Windows loads DLLs, it can find another dll of the same name on its search path and use that instead, leading to problems if the dependencies differ. One user found that uninstalling OneNote produced this error and reinstalling fixed it, so it seems other applications may use versions of that dll.

Installing the latest Oracle Java 8 runtime might also help, even though REW doesn't use it.

Thanks for the quick answers. I will first try to install an older release on a old macbook air. If that fails I will look into awt.dll instances.
