as3 debugger not starting in 5.3.0.3

[romamik]

I've just installed new flashdevelop version and get this error, when trying to start as3 debugger:

Debugger startup error. For troubleshooting see: http://www.flashdevelop.org/wikidocs/index.php?title=F.A.Q

Required file is present at path C:\Program Files (x86)\FlashDevelop\Plugins\jni4net.j-0.8.8.0.jar.
Looks like search path is url encoded while it should not.

As a temporary solution I've reinstalled FlashDevelop to C:\FlashDevelop and that solved the issue for me.

Please check development build from http://flashdevelop.org/downloads/builds/

[romamik]

It works as intended in development build...

PS I've installed it in standalone mode in parallel with my normal install

Development version 5.3.1.52

FlashDevelop x86 or x64? java x86 or x64?

[pzahra]

Definitely java x86, and it would be the x86 FD, too. I'm pretty sure I didn't try the x64 FD, I've had issues with that in the past.

Maybe this is fixed or improved in https://ci.appveyor.com/api/buildjobs/pb46pxtxd6362jce/artifacts/FlashDevelop%2FInstaller%2FBinary%2FFlashDevelopPR_1956.zip

Same with FD 5.3.1.27

@romamik can you please latest development build?

[SeanJD]

I'm also having this issue.
I tried the latest release build and was having the below error, found this thread, assumed the latest development build may fix it but it hasn't.

I'm running the development build: 5.3.3.42 and am getting the following stack trace::

Any ideas how to fix? Or troubleshoot, happy to check through and post back if anyone has any ideas of how to sort...
