I`m working for different customers for different systems (Sharepoint 2003, 2007, 2010) on different VS-Versions (not allowed to upgrade the v9 solutions to v10). So I have installed VS 2008 and VS 2010 side by side on my Notebook. But I can't install WSPBuilder
V1.04 side by side with V1.06, it says, that there is already an other version installed... So at this moment I have to uninstall the one version and install the other version when I go from one customer to the other.
Or does someone of you know a solution for this problem?
