Hi everyone, I noticed the runtime path was not included into the environment variables. After include the path "C:\Program Files (x86)\Appeon\Common\PowerBuilder\Runtime 21.0.0.1509" into the environment variables now my tool is working fine.

Hi Andy,

Since this is only happening to some of the machines, I suggest you use sfc to check if the system files are all right. Please refer to:
https://www.appeon.com/developers/get-help/knowledgebase/how-examine-and-fix-corrupted-machine-system-files.html 

Also, I suggest:
1. Install PowerBuilder Runtime on the client and see if the issue is gone. You can refer to the link below for installing PowerBuilder Runtime.
https://docs.appeon.com/pb2021/application_techniques/Deploying_Applications_and_Components.html#Installing_PowerBuilder_Runtime 
2. Add a pb.ini file to the directory where your PBapp.exe resides, and this file contains the following content.
[Data Window]
ACCESSIBILITY=0
3. Run your application with Run as administrator and see if it works normally.

Regards,
Ken

Hello Chris,

we have similar problems in two of our appliactions (PB2021.1506, random crashes on some customer clients). We want to try your suggested solution with the PB.ini.

What exactly must the PB.ini looks like? In which section of the INI do we need to insert the "accessibility=0" option?

Thanks for your support.

Best regards

Heiko

Chris,

I will try your recommendation and let you know the results.

Thanks,

Andy

Armeen,

Yes, we are deploying the correct runtime DLL's.  The crash does not happen with all installs, in fact only a few.  The installs where the crash happens, only running in compatibility mode seems to correct the problem. 

I will try Chris's recommendation of adding a pb.ini with accessibility=0 on the users that experiencing the crash.

Thanks,

Andy

Are you sure on the machines that have problems the runtime DLLs have been upgraded to 2021 version?  This is common cause of crash issues after upgrading.

Hi Andy;

  You can also try creating a custom PB.ini file and copying this to your App EXE's deployment folder. In this custom INI set the Accessibility=0.
