Change listener connetion error

“The Microsoft Dynamics NAV Server cannot connect the Change Listener to SQL Server because of the following error: user ‘NT AUTHORITY\NETWORK SERVICE’ failed when log in”.

This error may happen when you are attaching the database manually, or if database and NAV service is on two different machines. A variation of this may also happen if you setup NAV server to user domain user account. Luckily the solution is the same for all problems

How do you define a good installer?

Did read Christopher Painter blog “Back To Basics – Installation Principles” today. It contain some very basic rules of creating an installer. In his blog he lists 14 point of what to avoid and what you installer should do to be a good installer? I have personally seen big problem rise from his advice number 12 about using standard installation part and avoid using you home maid as much as possible. So to make it short, I think every installer developer should really look into this list to avoid doing the same mistakes.

And here is the list copied from Christopher.
1) Remember that your install is the very first impression the user gets of your application. If your install sucks or worse fails that will not want to use your software or your support desk will get flooded with calls. I can not understate this point. I have saved companies from the brink of bankruptcy by fixing their deployment problems and I’ve seen companies fail that were unwilling to take their problems seriously.

The pain of .NET “AnyCPU” build typ for installers

Today I found an interesting post about why we should avoid using “AnyCPU” as build type when we are building managed assemblies. The problem simple is that when installing the application and are writing registrie key we need to define if it’s a 32 bit or 64 bit application in the MSI. You can build an EXE as “AnyCPU” and on an x86 windows machine it will run on the 32bit CLR and on an x64 windows machine it will run as a 64bit process.

Christopher Painter gives this example on his blog post to explain the problem:
So let’s start with a simple example. Let’s go back 10 years in time and pretend we are writing an x86 application and x86 installer with no concern for x64. Someone hands you a vb6 EXE and a regfile ( HKLM\SOFTWARE\Company\Product type entries ) and says this is what needs to be deployed. You go off and create an MSI that writes the registry values, deploys the EXE and creates a shortcut. Now let’s come back to present. You take that MSI and throw it on a modern Windows 7 x64 box and it works just fine.

But now let’s pretend that the EXE was a .NET application. If it was compiled as x86 it would behave the same way. But if that application was built at AnyCPU ( the default for all versions of Visual Studio prior to VS2010 ) we are going to land in one of those traps. Here’s why:

MSI is marked as an x86 package so it writes the registry data to the Wow6432Node of the registry so the expected x86 application can find it. While the EXE gets installed to ProgramFiles(x86) it will actually JIT as a 64 bit process. This process will fail to find it’s registry resource at runtime and crash. This is because the .NET BCL Win32.Registry class cares about bitness.

The “OK” button is greyed out on RTC server selection window

Did decide to write this blog since this simple problem did take a lot of time for me to find the solution for, in the hope that it will save you from the same time eater.

The problem I did run into was that when starting the RTC client it could not connect to the service, since I had moved the service. Since the service had moved I did say “no” to the questions if RTC should try to connect again. In the address field in the “server selection window” I did type the new address into address field. The “OK” button was now greyed out, so I could not connect to the server.

After spending some time to try to figure it out how to un grey the “OK” button I found by simple press TAB in the address field make RTC to connect to the service and retrieve the companies on the service. Now the “OK” button was not greyed out anymore.

Dynamics NAV RTC hangs when previewing/printing reports

When previewing a report you only getting a small window in upper left corner with only a text string with the name for the report and the rest blank. When I trying to close this window, you get an error message: “Errors exist. Do you want to discard changes?” (Y/N). Pressing Yes, hangs and close the RTC client.

Probably cause:
You have installed the RTC client outside the setup chainer or you have uninstalled Report Viewer 2008. It may also be that Report Viewer 2008 installation is broken.

Run DVDPrerequisite ComponentsMicrosoft Report Viewer 2008 ReportViewer2008.exe and select install or repair depending on if Report Viewer 2008 was already installed.

Ensure also that the license is uploaded.

4. Click upload and pick the license file to be uploaded to SQL server

Ensure also that the license is saved in the database.

“User ID and password are invalid.try again?”

If you get “User ID and password are invalid.try again?” when starting RTC you need to first check that you can login to database in the classic client. Note that the database should be the same as the service tier (the service you are trying to connect with RTC) is connected to.
1. Start “classic client with SQL”
2. Click File->Database->Open
3. Pick the server the database exist one
4. Select authentication “Windows Authentication”
5. Pick the database
6. Press OK

If it works in the classic client make database login synchronization.
1. Start “classic client with SQL” and connect to the database as above
2. Click Tools->Security->Synchronize all logins
3. Answer yes to the question if you would like to synchronize

If it doesn’t to connect to the database start SQL server manager and verify that the windows user have permission to login and use the NAV database
