I have just had a test on my Windows Server 2008 and verified that there will be a big problem if you remove VC redist 10 at first.
Here is the problem description and how I got over the problem, the following part is especially for those DTG guys who are interested in troubleshooting setup problems.
Unable to uninstall .NET Framework 4 Client Profile Beta 1, and cannot install/repair previous versions of .NET Framework such as .NET 2.0/3.0/3.5/3.5 SP1, and even cannot make event viewer work!
Event viewer or other administrative tools will leave such an error:
MMC could not create the snap-in. The snap-in might not have been installed correctly.
name: Server Manager
CLSID: FX:{18ea3f92-d6aa-41d9-a205-2023400c8fbb}
Yes, you got so in trouble.
But wait, let's check out the installation log to see if we can get any clue, we go to %temp% and look for Microsoft .NET Framework 4 Client Profile Beta 1 Setup*.html and Microsoft .NET Framework 4 Client Profile Beta 1 Setup*.txt.
You will see the setup failed at the CommandLine = "C:\Windows\Microsoft.NET\Framework\v4.0.20506\SetupCache\Microsoft .NET Framework 4 Client Profile Beta 1\Setup.exe" /repair /x86
It is not enough, exploring further we will investigate the details at Microsoft .NET Framework 4 Client Profile Beta 1 Setup*.txt
Trying searching for "return value 2" to find the vital error(s)(I'll give explanation later)... the relevant part was:

Action ended 12:55:18: InstallExecute. Return value 2.
Now there is some clue that the problem was happening at the bold command line i.e. C:\Windows\Microsoft.NET\Framework\v4.0.20506\ngen.exe uninstall
Then, I tried running the command line manually, it gave me the error:
This application has failed to start because MSVCR100.dll was not found.
Re-installing the application may fix this problem.
Oh, yes, we were approaching to the root cause!
The problem was the missing file MSVCR100.dll, that is to say it was actually complaining about the VCredist 10 beta 1 cannot be found there.
Rather than reinstall all of VS 2010 Beta 1, we can try to reinstall the .Net Framework 4 beta1 to get it back, for there is no standalone VCredist 10 available. We can get .NET Framework 4 installer at <VS2010 installation source>\WCU\dotNetFramework\dotNetFx40_Full_x86_x64.exe
Well, the solution however is simple: reinstall .NET 4 beta 1 and then remove them in the order.
As for "return value 2", it refers to "User canceled", 0 for Action not executed;1 for Success;3 for Fatal error and 4 for Suspended, waiting for reboot.
Usually we search for "return value 3" which probably can speed up the job, but in this case the user was forced to cancel the setup for runtime errors, so there is no value 3 but 2.
