When I try an install GoSilverlight1104.msi it says:
“Another version of this product already exists”

I have GoSilverlight1.1.0.3 installed for use with Visual Studio 2008 and Silverlight 3. I also have Visual Studio 2010 installed and am using the Silverlight 4 beta. I want to use the version here.

I need to work with both environments and according to the list of installed programs only the is installed.

Can I do this?


Oops, I must have forgotten to increment some MSI GUID. Thanks for pointing it out.

There shouldn’t be an issue with having both installed at the same time.

I suppose you could copy the directory with the installation, uninstall, install, and then copy back the original installation.

Or I could just give you the files ZIPped.
