Hi Daniel,

On windows, when I need to do a single folder installation, i just copy all the content of the firstruninstall folder and paste it one level up, i.e. on the root directory where Omnis.exe is. 

If I need to do a split installation, I place our liberties in the firstruninstall folder then all the content of the firstruninstall will be copied to the user’s appdata folder. 
If you want a single folder install and you want to avoid the read/write restrictions in “windows”, then avoid installing Omnis on  c:\programfiles.

Hope that helps,
