Hi
You could try the following, found on sourcelink. however normally your env file will contain a reference to telenv
The Layout to Allegro translator will only run on computers that have Allegro installed on them. Because the VIF interface into Allegro wants to assess your ENV file before doing the translation, you must have a Windows NT environment variable named TELENV pointing to your Allegro ENV file. Typically, a copy of the ENV file can be found in the \SHARE\PCB\TEXT path.
To set the TELENV environment variable, right-click on the My Computer icon on your desktop and choose Properties from the pop-up menu. Choose the Environment tab, enter TELENV in the Variable text box, enter the path where the ENV file is located in the Value text box, then click Set. You should see a new entry that is similar to the following, depending on your installation location:
TELENV C:\CADENCE\SHARE\PCB\TEXT\ENV
Best regards
