How to install sensenet 6.5 from web deployment package How to install sensenet 6.5 from source package


In the following sections, we’ll provide solutions for the most common errors you may encounter during the installation process. Don’t let these intimidate you - all of these obstacles can be easily tackled!

Cannot connect to SNCR

Check the web.config file: look for the SQL connection string and see what user name and password was added there during the install process (it should not be the sa user but a custom account like sensenet6). This user should have access to the database that is also added to the connection string. Here’s a forum topic that might be helpful.

‘Deploy’ menu item does not appear in IIS

First of all, please make sure that Web Deploy 3.5 or later is installed on your system. If so, try restarting the IIS console. If the above still don’t resolve the issue, go to Add/Remove programs in Windows and remove Web Deploy 3.5. Once it’s done, install Web Deploy 3.5 Hosting for servers. Still having trouble? Try installing from this link, by choosing Typical.

404 error after a successful installation

First of all, check the port number: it should be set to 80. It is? In this case, the most common cause is that there is something wrong with your .NET framework. Please try reinstalling it. Still get the error? In some cases, it turns our that the order in which you install the .NET framework and IIS is relevant. You will probably need to register IIS. You can either do it with running the following command:

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

If running a 32 bit system, it should look like the following:

%windir%\Microsoft.NET\Framework\v4.0.21006\aspnet_regiis.exe -i

or you can download an exe from Microsoft to do it for you.

Blank page on Default.aspx after installation

Your application development features might not be turned on in Windows. To resolve:

  1. Press Windows key
  2. Type Turn windows features on or off
  3. In the features window, click Internet Information Services
  4. Click: World Wide Web Services
  5. Click: Application Development Features
  6. Click to enable features (ASP and CGI are not needed for sensenet).

Error 500 - Internal server error

Error 500 after a successful installation usually means a problem with aspnet+iis binding. The best way to figure it out is to show the error message itself, by editing the web.config and setting the following: - uncomment and set customErrors mode to off - comment out the full httpErrors section This way you will receive a more detailed error message and will have a better understanding of what you are looking at. A common error is that ASP.Net is not completely installed with IIS, even though you checked that box in the Add Feature dialog. To fix this, simply run the following command at the command prompt

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

If running a 32 bit system, it should look like the following:


Error: Unable to load one or more of the requested types.

Error: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information

Unblock libraries

If the installation or site start fails because of dll load errors than make sure that all dll files in the Tools, bin, and References folders are unblocked. You can unblock files in a single folder using the Unblock-File command in Windows PowerShell:

dir "C:\SenseNet\References" <nowiki>|</nowiki> Unblock-File
dir "C:\SenseNet\Source\SenseNet\Website\bin" <nowiki>|</nowiki> Unblock-File
dir "C:\SenseNet\Source\SenseNet\Website\Tools" <nowiki>|</nowiki> Unblock-File

Missing library

There is a chance that there is a missing library in the environment - maybe one of the external libraries or a 3rd party plugin. Do you get the above error message after a successful install? Please make sure if all dlls are present in the web\bin folder and (in case you get the error when executing a tool, like IndexPopulator) the web\Tools folder, especially these:

If you cannot find any one of these, download the source package and copy the dlls manually from the References folder. If the portal runs correctly and you get this error executing a tool in the web\Tools folder, you may try to copy the missing files from the web\bin folder to the Tools folder as a workaround.
