If you want to install vCenter 4.1 on Windows 2008 Server R2. You might get the following error:
This time the solution is simple. From: KB1013530:
When installing vCenter Server 4.1 on Windows 2008 Server R2, the installer completes but the installation fails.
You receive the error:
Error 28035.set up, failed to copy DSACLS.exe from system folder to %winder%\adam,folder
The solution is simple:
Some versions of Windows 2008 R2 may already have this component installed. However, it may be necessary to add the Application Server role in Server Manager or simply enable .NET Framework on Windows 2008 R2. To verify that the .NET Framework is enabled, go to Server Manager > Add Features > .NET Framework 3.5.x Features.
Or you run the dism command line tool:
dism.exe /online /enable-feature /featurename:NetFx3
More info about dism.exe can be found here: http://technet.microsoft.com/en-us/library/dd799258(WS.10).aspx
When you’re done installing the .Net Framework 3.5.x you are able to install vCenter 4.1 on Windows Server 2008 R2.
Oh and don’t forget to use the Native SQL client 2008 and the 32bit DSN like I mentioned in my earlier post.
