Hi guys, some new users may encounter "value creation failed at line..." problem when using logonstudio, most possible reason for this is that the language is not English in your computer. To solve this, there are four steps:
1) uninstall logonstudio.
2) Change the language to English in the advanced setting in 'region and language setting' which you can find in control panel. Restart if needed.
3) reinstall logonstudio, and set the logon skin you like. Click apply to see whether it works or not.
4) restart computer. now the logon skin should work.

If you still want to set the language back to original, you can change that after the logon skin is already working. The new change of language will not influence the logon setting anymore.

Enjoy!
