Allow multiple versions of a managed assembly dll to be installed in the GAC ?
Hi,
I need to be able to install multiple versions of my simple single .dll file managed assembly but when I run the installer I have created for the product it always requests that the previous version is uninstalled first. Is there any way to get ISLE4VS to generate an installer which will permit multiple versions of the managed assembly to exist in the GAC at the same time ? The attribute which I am using to determine the Assembly version is AssemblyVersionAttribute.
Thanks,
Mike Davies

Hi Mike,
It seems like there is 2 different issues here.
Are you trying to perform a upgrade? If you are, try building with a setup wrapper or pass in REINSTALL and REINSTALLMODE with the value you want via the command line. The setup wrapper passes those in automatically.
I think you might need access to the MsiAssemblyTable if you want multiple versions of the same file to go into the GAC.
