JSharp Runtime 2.0 could not be installed  
News Group: embarcadero.public.delphi.install

Hi 
I´ve been trying to install delphi 2010 on a windows 2003 server x64 edition with service pack 2.
I already have delphi 2007 installed on this server.

First when the installation process starts I get the message "Your system lacks the following prerequisites required to install Embarcadero RAD studio 2010.  Microsoft JSharp Runtime 2.0"  
Then I continue the wizard and install J#.  But I get an error after a little while saying "JSharp Runtime 2.0 could not be installed.  Please use Windows Update to manually install this update on your system.  Embarcadero RAD studio setup 2010 cannot continue.
When this error happens, the installer is executing "C:\windows\Microsoft.NET\Framework\v2.0.50727\ngen.exe update / queue"

I have installed all the windows update available but that does not help me.

Does anybody have any solutions for me?

I´ve tried that.  First I uninstalled all my .NET redistributable packages and all the J# redistributable packages.

Then I downloaded +Microsoft .NET Framework Version 2.0 Redistributable Package (x64)+ and +Visual J# 2.0 Redistributable Package-Second Edition (x64)+ packages and installed them manually.

When I started the delphi setup, I still got the message that I needed to install Microsoft JSharp Runtime 2.0.  

Any more ideas?

You will need to install the x86 version of the .Net 2.0 framework and the J# 2.0 runtime.

I have solved this problem.

All I had to do was to right click on the setup.exe file, and run as administrator.

The user I used to try this before had a full administrative rights, but that was not enough.

Brynjar, I have the same problem, however your solution didn't work for me.  I have an x64 Windows 2003 server with Service pack 2.
I have managed to get the SDK installed, so the only thing remaining is the JSharp Runtime.  The runtime seems to be installed already, though, so I would like a way of tricking the system into accepting the installation.   As I understand it, J# runtime is used for Together which I don't use much anyway.  Did you come across others suggestions that worked for somebody else?

Also, the exe you are referring to, is that the CodeGearRADStudio2007setup.exe, or a separate install for the JSharp runtime (which seems to be called vjredist64.exe here).

I've just run into this problem installing Delphi XE on a 2008 R2 Enterprise 64-bit system.  Seems the solution mentioned here (the symbolic link) fixed it right up.

I ran this .NET clean-up tool and it worked wonders.

Hi All.

I only test on Windows 2003 Terminal Server.

Go to Control Panel and add/del programs and select Jsharp.

Select the option restore, don´t close it and run again the embardero install.

It´s very crazy but work.

This solution worked for me installing XE2 on 2008 64 Bit Terminal Server. Thank you for posting it!
