Framework 1.1 /2.0 Controls Hosted in Internet Explorer

Hi All,
I have a windows forms controls hosted in IE via the object tag
method. The control was built to run on 1.1 of the framework and works fine
whilst version 2.0 is not installed on the machine. When version 2 is
installed the executables are downloaded to the 2.0 temporary directory, even
though the assemblies where build under 1.1 and are referencing the 1.1
framework. That is, when 2.0 is installed they are downloaded to Documents &
Settings\<CurrentUser>\Local Settings\Application Data\assembly\dll3 instead
of Documents & Settings\<CurrentUser>\Local Settings\Application
Data\assembly\dll2.

Could anyone tell me if there is a setting to force IE to use the 1.1 temp
download cache? Or is it another assembly setting?

I have tried setting
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\OnlyUseLatestCLR=dword:00000000
- but it has no effect.

TIA
