Question
How do you manually clean Software Virtualization Solution from a client computer?

Answer
Manually cleaning up a computer is a simple matter of cleaning up everything the installer does. Start out by removing all the files and registry keys listed below:

• C:\Windows\system32\drivers\fslx.sys
• C:\Windows\system32\fsllib32.dll
• C:\Program Files\Altiris\Software Virtualization Agent\AltirisVSProvider.dll
• C:\Program Files\Altiris\Software Virtualization Agent\AltirisVSProvider.mof
• C:\Program Files\Altiris\Software Virtualization Agent\svscmd.exe
• C:\Program Files\Altiris\Software Virtualization Agent\svsadmin.exe
• C:\Program Files\Altiris\Software Virtualization Agent\<LANGUAGE>\svsadmin_resources.exe
• C:\Program Files\Altiris\Software Virtualization Agent\fslui.dll
• C:\Program Files\Altiris\Software Virtualization Agent\<LCID>\fslui_resources.dll
• C:\fslrdr
• HKEY_LOCAL_MACHINE\SYSTEM\Altiris\FSL
• HKEY_LOCAL_MACHINE\SYSTEM\Altiris\SVS
• HKEY_LOCAL_MACHINE\SOFTWARE\fslrdr

Delete the FSLX driver with the following command:

sc.exe delete FSLX

Removing the WMI Provider is a little more complex. You can use a built-in tool named wbemtest.exe for this purpose. Launch the tool, click the Connect button, enter the namespace "root\default" and click Connect. Click the Delete Class button, enter the class name "AltirisVSProv" and follow the prompts to delete the class. For completeness, also remove the registry keys created by the WMI provider:

• HKEY_CLASSES_ROOT\AppID\AltirisVSProvider.DLL
• HKEY_CLASSES_ROOT\CLSID\{71D8DF9A-AD2D-44BF-A542-1412F68061D1}
• HKEY_CLASSES_ROOT\TypeLib\{888967EF-E75C-4480-992D-93FDA658F21E}

The final step is to cleanup the stuff that Windows Installer caches about the package. The easiest way to do this is with a tool called msizap.exe from the Windows Installer SDK. The following command will remove all Windows Installer data for the SVS Agent:

msizap.exe TW! {7D8DBB7C-1C55-4950-A107-043C164F379A}
