Syncfusion Assembly Manager Error

[Administrator]

If I try to install the Syncfusion Essential Studio 3.2.1.0, I get following error message: --------------------------- Syncfusion Assembly Manager --------------------------- There was an error updating at least one Syncfusion assembly. A log file describing the exception has been placed at "D:\Program Files\Syncfusion\Essential Studio\3.2.1.0\Utilities\Assembly Manager\2003\assemblymanager_error.log Please close any process that may be using the assembly and run this utility (The Syncfusion Assembly Manager) again. If the problem persists, please contact Syncfusion Technical Support ([email protected]). We apologize for the incovenience. --------------------------- OK --------------------------- The log file contains following: System.NullReferenceException: Object reference not set to an instance of an object. at SFAssemblyManager.SwapUtilityDlg.On_Ok(Object sender, EventArgs e) at SFAssemblyManager.SwapUtilityDlg.OnIdle(Object obj, EventArgs e) at System.Windows.Forms.ThreadContext.System.Windows.Forms.UnsafeNativeMethods+IMsoComponent.FDoIdle(Int32 grfidlef) at System.Windows.Forms.ComponentManager.System.Windows.Forms.UnsafeNativeMethods+IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.RunDialog(Form form) at System.Windows.Forms.Form.ShowDialog(IWin32Window owner) at System.Windows.Forms.Form.ShowDialog() at SFAssemblyManager.SwapUtilityDlg.Main(String[] args) I checked the assembly cache, following two assemblies are installed: * Syncfusion.Compression.Base * Syncfusion.WebServer Then I tried to install it with the Assembly Manager, but I get the same exception: System.NullReferenceException: Object reference not set to an instance of an object. at SFAssemblyManager.SwapUtilityDlg.On_Ok(Object sender, EventArgs e) at System.Windows.Forms.Control.OnClick(EventArgs e) at System.Windows.Forms.Button.OnClick(EventArgs e) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) Additional Issue: In the Assembly Manager the check box "Update VS.NET 2005 Toolbox" is greyed (only "...2003..." is enabled). But I habe VS.NET 2003 and VS.NET 2005 Beta 2 installed. Reinstallation (with and without uninstall) doesn''t solve the problems.

I have the exact same problem.
I try to re-install many times but it doesn''t fix the problem.
