I have an application needed to be installed in my computer but it requires installing the .NET Framework version 1.1. When installing the Dotnetfx.exe I received an error that is related to RegSvc.exe.

RegSvcs.exe - Common Language Runtime Debugging Services

Application has generated an exception that could not be handled.

Process id=0x18a8 (6312), Thread id=0xef4 (3828).

Click OK to terminate the application.

Click CANCEL to debug the application.

I need to have this version of .NET Framework. I am installing other version of QuickBooks .Can someone knows how to fix this error or somewhat suggest me another alternative?

Hi Kim

This error is usually seen when installing .NET Framework. And the set up fails to register the System.EnterpriseServices.dll or has a problem running RegSvcs.exe /bootstrapi which then also cause the installation to not continue and rollback the process.

You might want to try this work around:

Download .NET Framework cleanup tool and run it.

Locate HKEY_USERS\.Default\Control Panel\International and verify that the data in the registry value is already valid. The registry value should have at least one of the values located at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Nls\LocaleMapIDs. Now get a crash dump in Microsoft Windows Debugger that registers System.EnterpriseServices.dll.

Most of the time running this cleanup tool fixes the problem and if not you should already report it to windows. Hope this helps you. Thanks!

Use the cleanup tool to remove unwanted files due to a failed installation or just to remove any damaged or corrupted files associated with the software. Here is a user guide with the links on how to go about the process:

Download .Net Framework Version 1.1 and .Net Framework SP1 here:
 http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=26
 http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=33
Create a folder in C:\ named MSDotNet and have both file saved there. Open the command prompt (cmd) as Administrator and cd to c:\MSDotNet and execute these commands:
 dotnetfx.exe /c:"msiexec.exe /a netfx.msi TARGETDIR=C:\MSDotNet"
Just hit Yes and wait until it's finished.
 dotnetfxsp1.exe /Xp:C:\MSDotNet\netfxsp.msp
 msiexec.exe /a c:\MSDotNet\netfx.msi /p c:\MSDotNet\netfxsp.msp
Wait for the installer window to disappear automatically then run netfx.msi to install .Net Framework 1.1.
