Upgrade a 32 bit WCCOA 3.11 SP1 project to 64 bit WCCOA 3.11 SP1

[ragrawal]

I have a project running on a windows 32 machine with PVSS 3.11 SP1 (32 bit version) and want to run it now on another windows 64 bit machine with WCCOA 3.11 SP1 (64 bit version). How this can be done?
Thanks.

Hello,

there is no upgrade procedure necessary when copying a project from 32bit-machine to 64bit-system.
If you are using own API-managers or dll-files you have to install the 64bit-version for these files.

Thank you for the reply. But can a 32 bit project with older version (3.9) be upgraded to 3.11 sp1 on 64 bit machine?
I am getting some error in upgrading the project. Please see the screen shot attached.

Thanks.

Hello,

we cannot see the attached screenshot.
The upgrade of 32bit-project on a 64bit-machine is possible.

If you get errors during the upgrade please refer to the official WinCC OA support and submit a service request.
