Error Code error-envvar-not-found — Windows 11

Postup řešení

1. 1 First, identify which environment variable is missing. The error message may specify it, or you can check the program's documentation. If not, you can use a tool like Process Monitor to see what the program is looking for, but that's advanced.
2. 2 Open the Environment Variables editor. Press Windows key + R, type 'sysdm.cpl', and press Enter. In the System Properties window, click the 'Advanced' tab, then click 'Environment Variables'.
3. 3 In the Environment Variables window, you'll see two sections: User variables and System variables. Look for the missing variable in both lists. If it's not there, you need to create it. Click 'New' under the appropriate section (usually System variables if it's needed for all users).
4. 4 Enter the variable name and value. For example, if the program needs a variable called 'MYAPP_HOME' pointing to its installation folder, type 'MYAPP_HOME' as the name and the full path (e.g., 'C:\Program Files\MyApp') as the value. Click OK.
5. 5 After adding the variable, you may need to restart the program or even the computer for the change to take effect. Close and reopen the program that was failing.
6. 6 If you're unsure what value to use, check the program's documentation or contact the developer. Alternatively, you can search online for the specific error and program name.
