Microsoft CRM 3.0 Installation Failure




 I am currently trying to install on new CRM 3.0 SVR but near the end of the installation I’m receiving the following error:
Activating SQL Server Reporting Services Failed.
Setup failed to validate specified reporting services report server http://CRM/ReportServer, Error: Object reference not set to an instance of an object.
Is the SQL Server Reporting Services installed on the CRM server? Sounds like SSRS isn’t setup correctly.
hi [@gianna.demetroulakos](/u/gianna.demetroulakos),

as mentioned by [@william.coulson](/u/william.coulson), the object reference not set to an instance of an object normally occurs when a variable is null.

run the code in the debug mode.

when the error occurs, check the variable which has a null value in locals tab.

warm regards,

ranjith u… that error happens when there's no handle to close. i see you call the 'open()' and you're not getting an object reference error before closehandle(). check your memory.pointerwrite() function to make sure it's not doing a closehandle() prematurely. it sounds like you're calling closehandle() twice. Hi  

This is simple. First check whether you are able to connect Sql Server through SSMS or not.If you are able to connect through SSMS, then there may be a problem in connection string. If you are not able to connect through SSMS, then you had some problem with SQL Environment. hey [@emartini](/u/emartini) ,

if you want to use clij2, you also need to activate the clij update site. the error should be gone then.

see also the [installation instructions](https://clij.github.io/clij2-docs/installationinfiji).

let me know if this solves the issue!

cheers,

robert need to add 



```
services.AddEntityFrameworkSqlite().AddDbContext<ApplicationDbContext>();

```

and delete



```
services.AddIdentity<IdentityUser, IdentityRole>()
                    .AddEntityFrameworkStores<ProductContext>();

```

in startup.
the error was about bad startup configuration.
Was sending too much things.


ApplicationDbContext:



```
 public class ApplicationDbContext : IdentityDbContext
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
            : base(options)
        {
        }
        public Microsoft.EntityFrameworkCore.DbSet<Product> Products { get; set; }
        public Microsoft.EntityFrameworkCore.DbSet<List> Lists { get; set; }

        public Microsoft.EntityFrameworkCore.DbSet<ProductList> ProductLists { get; set; }


        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            base.OnConfiguring(optionsBuilder);

             optionsBuilder.UseSqlite("Data Source=assistant.db");

        }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {

            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<ProductList>()
                .HasKey(pl => new { pl.ProductId, pl.ListId });

            modelBuilder.Entity<ProductList>()
                .HasOne(pl => pl.Product)
                .WithMany(p => p.ProductList)
                .HasForeignKey(pl => pl.ProductId)
                .OnDelete(DeleteBehavior.Cascade);

            modelBuilder.Entity<ProductList>()
                .HasOne(pl => pl.List)
                .WithMany(l => l.ProductList)
                .HasForeignKey(pl => pl.ListId)
                .OnDelete(DeleteBehavior.Cascade);
        }
    }

``` welcome rm.  the smtp server listed in the post is the correct one.  the is a short time lag between account creation and full activation on the server. please retry the outlook set up again and let us know if it successful. 
 
thank you hola, acabo de solucionar mi problema

problema:

[unhandled promise rejection: error: no native splash screen registered for provided activity. please configure your application’s main activity to call ‘splashscreen.show’ ([https://github.com/expo/expo/tree/master/packages/expo-splash-screen#-config…](https://github.com/expo/expo/tree/master/packages/expo-splash-screen#-configure-android) strangely enough it did in a strange way. i reinstalled, set up everything again from scratch (agents too) and got the same ‘not connected’ error.

i got frustrated and left it overnight.

the following morning in the office i checked and it discovered both services!

so i guess you could close this… For anyone having similar problems, I have solved my issue. It was several-fold.


* As Darren suggested and Paul backed up, the Max..Size properties in the configuration needed to be enlarged. The SvcTraceViewer utility helped in determining this, but it still does not always give the most helpful error messages.
* It also appears that when the Service Reference is updated on the client side, the configuration will sometimes not update properly (e.g. Changing config values on the server will not always properly update on the client. I had to go in and change the Max..Size properties multiple times on both the client and server sides in the course of my debugging)
* For a DataTable to be serializable, it needs to be given a name. The default constructor does not give the table a name, so:



```
return new DataTable();

```

will not be serializable, while:



```
return new DataTable("someName");

```

will name the table whatever is passed as the parameter. 


Note that a table can be given a name at any time by assigning a string to the `TableName` property of the DataTable.



```
var table = new DataTable();
table.TableName = "someName";

```


Hopefully that will help someone. if drivers are uptodate it will not show onto the list. else start the utility with 'run as administrator' option and see if it's working.
