Conflicting GDP versions in multiple apps

Post by aleung » Thu Aug 22, 2013 10:37 pm

We have a situation where a customer has an existing vb6 application that is using the COM version of GDP v9.1. We install our vb6 application that is using the COM version of GDP v9.4. When we do that, it breaks their existing application using GDP v9.1. Does anyone know how we can distribute our application so that it does not break their existing application?

Hi,

side-by-side installation is not possible, because of the strong name, installing another version of the same main version number when one is already installed will overwrite it (which is wanted). Cohabitation is possible only between major versions, like 12.x and 14.x installed at the same time, they will both work fine.
