Workbench throw an exception when compiling basic code.
I just can't work !

I can connect to the real AKD and control it but no way to compile any code.

I tried to create an empty project with a simulated AKD-BASIC and compile an empty code file with the same result.

I tried to uninstall and reinstall, tried an older version

How can i make it work ?

After a deeper investigation, the problem is due to accented characters (eg. "é", "è", "à" - commonly used in French/German/...) used in the path of BASIC program files.
The actual WorkBench/BASIC compiler combination does not support them, it could run into an infinite loop or eventually throw an exception.

For an immediate resolution, please avoid any of these accented characters in your path or filename in relation with your BASIC program.

In future WB versions, we plan to:

  • Try to have full support for the accented characters
  • If not possible:
    • Check for accented characters and inform the user
    • Eventually use a temporary folder to do the compilation and put back the compiled file in the accented path (transparent for the user)
    • Timeout compilation to recover gracefully in case of problem.

A big thanks to Nicolas who helped me a lot to find the root cause of the issue.

This is probably an installation issue - the BASIC compiler is using VC 2010 SP1 redistributable files (v10.0.40219).
When you install WB, in normal cases, if these files are missing, they will be installed.
Not sure if you canceled anything during the install.

It is also possible that your computer is in a bad state with these redistributables settings.
Please check what is installed on your computer - eventually uninstall/reinstall (only the VC 2010 redistributables).

You could try to reinstall them:
https://download.microsoft.com/download/5/B/C/5BC5DBB3-652D-4DCE-B14A-475AB85EEF6E/vcredist_x86.exe

Please let us know if it fixes your issue or not.

Thanks.This is not vcredist.
It was already intalled.
Your link is not the latest version of VC 2010 redist. I tried this specific version with no success.
The result is the same exception.

Could you please tell me the exact version of vcredist installed on your computer ?
I will do a try to see if it can cause problem - sometimes having newer vcredist could be a problem.
I tried to run WorkBench without the vcredist, I get the exact same exception as you get - this is why I'm thinking it is the problem.

I tried after uninstall VC 2010 redist and yes, this is exactly the same result.
I confirm that the result is also the same with VC2010 redist SP1 (V10.0.40219) and VC2010 redist (V10.0.30219, your link).
