Microsoft .net Reinstall Problem

OS=winxpsp3


Due to some problems in API for Gemalto GCR5500 smart card reader, I was advised to reinstall .NET subsystem.


Complete uninstall was succesfully (with Microsoft .Net Framework Setup Cleanup utility).


When I start dotnetfx35_SP1_full installation, it failed.


I try to install .NET one by one.


dotnetfx_1_1.exe succeed


dotnetfix_1_1sp1.exe succeed


NetFx20SP1_x86.exe failed


After some investigation of log files (VSSWMSIFailInfo.txt):


....


11/22/12 14:49:57 DDSet_Error: Failed to install assembly 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Drawing.Design.dll' because of system error: process cannot access file because it is being used by another process


....


11/22/12 14:49:57 DDSet_Error: Failed to install assembly 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\System.Web.Services.dll' because of system error: process cannot access file because it is being used by another process


....


11/22/12 14:49:58 DDSet_Exit: InstallAssembly ended with return value 1603


and with ProcExp and FileMon (Sysinternals) I found that vsserv.exe catch dll immediately (in the moment, when .NET installation process put file on file system).


I temporarily suspended everything possible in BitDefender, but problem remain the same. I did not try to uninstall Bitdefender and retry .NET setup - this will be last option.


So, I need some advice.
