HI scarleto,
Please try the way below
Create a folder name "mytemp" under your site root, set it for property "TempDirectory".
<CuteWebUI:Uploader ID="uploader1" runat="server" TempDirectory="~/mytemp">
</CuteWebUI:Uploader>
Then do the settings below in your web.config <appSettings> section. Uploader will use the account what you set for to access the temp directory. for the test, please set it as an administrator user.
<add key="CuteWebUI.AjaxUploader.WindowsUsername" value="administrator" />
<add key="CuteWebUI.AjaxUploader.WindowsPassword" value="Your*Password" />
Also, it maybe a permission problem of the flash plug-in, you can disable the flash upload mode to try again.
protected override void OnLoad(EventArgs e)
{
uploader1.SetAdvancedOption(UploaderAdvancedOption.NoFlash, "true");
base.OnLoad(e);
}
Regards,
Ken
