RDM 8.2.0.0 crash at startup

What OS version do you use?

Hello, thank you for your answer.
I use Windows Seven Professional 64 bits, 8Gb RAM.

Do you have the .NET 3.5 installed?

I run Microsoft .NET Framework 4 extended and Client Profile

Make sure that .NET 3.5 is installed. .NET 4.0 is not backward compatible

... I don't find any 3.5 version for windows seven on the internet...

You right, this was built-in. Could you try to execute the application with the Run as Administrator?

... same result.

Could you try to unzip this version in a different folder like c:\RDM

Tried.
Fine until i re-add my datasource (ms sql on another server, integrated security, test server ok, test database ok)
It may be due to the last modification of a session, who could have caused a corruption in the db ?

This is really strange because it's an OS crash. RDM has a specific message box. Could you try to rename the config file remotedeskopmanager.cfg in %LocalAppData%\Devolutions\RemoteDesktopManager and use an Xml data source for a test

it's not crashing, this way.

It seems to be a problem with SQL Server. Do you have anything special installed?

The DB is on a Windows 2008 server, MS-Sql Server 2008 (version 10.0.2531.0), running also others DBs with no problem at this time.
Is it possible to delete the last modification in the DB, like the last modification of a session ?

What do you mean bu last modification? Is it only on your machine that you get this crash?
