When updating, you see an error message that says 'Xara Designer Pro+ could not be located on your system'
This could happen for a few reasons, either Xara is not able to read the location where your program is installed, or it perhaps could of been moved to another location.
To find out, we can take a look at the logs to see what exactly failed. You can see the Instructions on how to retrieve them by clicking here.
Reinstalling the program will fix this issue, instructions can be found here.
If you need to download again (which will also contain the latest update), you can do so by clicking here.
