Sources of VWL Problems

Common VWL Opening Problems

Missing PTC Vuforia

If you attempt to load your VWL file, you experience a message such as "Can't Open VWL Files". Usually, this is because you do not have PTC Vuforia for %%os%% installed. The OS won't know what to do with your VWL file, so double-clicking to load the file doesn't work.

Tip: If you don't have PTC Vuforia installed, and you know of another program to open your VWL file, you can try opening it by selecting from the programs listed under "Show Apps".

Incorrect PTC Vuforia Version

In other instances, your Vuforia Word List file version may not be supported by your version of PTC Vuforia. Installing the latest version of PTC Vuforia from PTC is recommended. This problem is predominately due to having a Vuforia Word List file version that was created by a newer version of PTC Vuforia than what you have installed on your PC.

Tip: You can sometimes get hints about the right program version by right-clicking on the VWL file, selecting "Properties", and looking at the version information.

Summary: In either case, the majority of problems opening VWL files are related to not having the correct software application installed on your computer.
