For those who have trouble installing the 1.1 version of .Net in Windows 7 (“application has generated an exception that could not be handled” error), the following steps from JasonFJ from this thread worked perfectly for me:
~ Create a new folder named DotNet in C:\ drive (C:\DotNet is used in this guide, you can change to any folder you prefer, but ensure that you use correct path in the following steps).
~ Download Microsoft .NET Framework 1.1 Redistributable Package. Make sure the setup file is saved as dotnetfx.exe .
~ Download Microsoft .NET Framework 1.1 Service Pack 1 (NDP1.1sp1-KB867460-X86.exe). Make sure that the file is renamed and saved as dotnetfxsp1.exe, so that the rest of the steps can be followed easily.
~ Move both installation files into the same directory (i.e. C:\DotNet), if youâ€™re not saving them together. Open command prompt as Administrator (Start > All Programs > Accessories > [right-click on Command Prompt and select “Run as Administrator]).
~ Change to the directory where the two installation setup files for .NET 1.1 are saved (i.e. C:\DotNet).
~ Run the following commands one by one, press Enter after each one.
dotnetfx.exe /c:”msiexec.exe /a netfx.msi TARGETDIR=C:\DotNet”
~ Then click on â€œYesâ€ when prompted to answer â€œwould you like to install Microsoft .NET Framework 1.1. Package?â€
msiexec.exe /a c:\DotNet\netfx.msi /p c:\DotNet\netfxsp.msp
That’s it. It apparently doesn’t work for everyone, but this was the solution that worked for me. Games/programs like Lord of the Rings Online (LOTRO) require .Net 1.1.
If this still doesn’t work, check out this thread at the LOTRO forums for other solutions.
