RadAsynceUpload does not have permission to write files

[NoobMaster]

i have a problem in uploading files via RadAsyncUpload when i open the page that contains the telerik upload controls

the following error rises -->

RadAsyncUpload does not have permission to write files in the TemporaryFolder. In Medium Trust scenarios, the TemporaryFolder should be a subfolder of the Application Path.

 

in localhost working fine but in my website does not work ,

so i contacted to the host provider and asked to set full permission to App_Data an the Target folder and sub folders so they set the permission and still i get the above error ,

then i set UseApplicationPoolImpersonation to True and impersonate to true in web.config but still no hope same error,

what can i do to fix this error 

note: before the host provider update iis to 10 the upload was working.

default folder is  App_Data\RadUploadTemp, Is this the way you like Folder? 

[NoobMaster]

yes thats the Temp Folder

App_Data Create and name a folder in the folder change Asyncuploader.

your errors means : Tempfolder placed in the main branch, so write in main branch is access deny
