I am trying to get my hands in PO development and design but whenever I open .ui files using Designer it gives following error Code (text): An error has occurred while reading the UI file at line 45, column 90: Expected '=', but got '>'. Do you want to update the file location or generate a new form? It happens for every .ui file from PO. I have version 5.5.1 if that matters.
Not sure if it matters, but you should try to use Qt 5.0.2, because there are compatibility issues with more recent versions of Qt Creator. Here is a link of the correct Qt version for PO
Okay it worked but the problem was not with the Designer. Don't use wget to download the files because it will mess the encoding. I had to manually edit some properties to get it working. Better yet, manually copy paste contents from git.
