How to resolve the "Failed to prepare a profile..." error when selling templates for customers to run themselves

[thewitcher1357]

I often encounter the error "Failed to prepare a profile..." when selling templates to some customers and the template runs very slowly (my other customers run quite fast). I have tried the following:
- Reinstall Zennobox
- Turn off the firewall
- Restart the wifi network and computer many times
But the customer's machine still has this error. I also tried searching on the Zennolab forum but haven't found a solution to this error. I have lost quite a few customers when I couldn't handle errors and I find it very annoying to sell a template without knowing when the customer will ask for a refund because of this silly error. It's also difficult for me to let you Ultraview via the client's computer to solve the problem, so is there any way for Zennoposter to completely handle this error?

The solution is to switch to another server in configs.
Customer should edit ZennoPoster.exe.config and ProjectMaker.exe.config files. from Progs folder in program directory and change all entries userarea.zennolab.com to userarea-us.zennolab.com (or userarea-hk.zennolab, userarea.zenno.io depending on which gives better connection).
The files can be edited in Notepad or any other text editor.
Also, Internet channel should not be fully loaded by other programs on customer side.
