I'm so sorry to send this email again. I need an urgent answer for this problem, and it seems that this mailing list is my last resort. This is my problem:
I have created an installer with "WiXUi.InstallDir". I need to check the install path that the user selects and not let him continue the installation if the path contains a space. The installation is continued when the user choose a path which does not contain a space, and I don't want to break the installation. How can I check this and inform the user that he must choose a path without space in it? I was told once that I may require a custom action, and I will be able to use the >< operators to check for the space. I found no good explanation about this. Can anybody help me about this more? Thank you very much.
