Update from 3.6 to 3.8 is failed

Hello

I have problem with latest update.
When I run 

FileVista/update.aspx

And click Next after I select previous version I see message box with following error:


ERROR

System.Data.OleDb.OleDbException: Field 'Subfolder' already exists in table 'PermissionEntry'
....

How to solve?
Do I really need to run Update script in order to update from 3.6 to 3.8 ?

Thank you

Actually there was a mistake in the original noticiation email.
We sent out a correction email but I guess you didn't receive it. 
No, you shouldn't run update.aspx if you are already upgrading from a v3.x version.

Thank you

I run the new FileVista

When I login I get following error:

[NullReferenceException: Object reference not set to an instance of an object.]
   GleamTech.Web.Controls.FileVistaControl.set_MaxZipFileSize(String value) +32
   GleamTech.FileVista.DefaultPage.Page_Load(Object sender, EventArgs e) +1023
   System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) +14
   System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +35
   System.Web.UI.Control.OnLoad(EventArgs e) +99
   System.Web.UI.Control.LoadRecursive() +50
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +627

How to solve this?

Please copy the newly added settings from FileVista.config from the new version package to your existing FileVista.config.
I mean copy the below which are missing:

  <add key="UploadMethod" value="Flash" />
  <add key="TemporaryFolder" value="~/App_Data/temporary" />
  <add key="DisableFolderExpandableCheck" value="0" />
  <add key="MaxZipFileSize" value="" />
  <add key="ShowFileExtensions" value="0" />
  <add key="ShowHiddenFilesAndFolders" value="0" />
  <add key="ShowSystemFilesAndFolders" value="0" />

I already fixed the problem.

I copied the old FileVista.Config and it missing some parameters.
So it is OK now :)

Thank you for this update!
