STEP 5 Installed on Windows XP 32-bit - "NO authorization found" Error

Hello everyone,

I recently installed Siemens STEP 5 software on a Windows XP 32-bit system. The installation process completed successfully, but when I try to launch the application, I get the following error message:

"NO authorization found. Terminating the application."

I'm not sure how to resolve this issue. I believe it may be related to licensing or authorization, but since this is an older software, I'm having trouble finding clear guidance.

Has anyone faced this problem before?

Is there a way to activate or authorize STEP 5 properly on Windows XP?

Any help or step-by-step guide would be highly appreciated.

Thanks in advance!
