Hello Markus,
In this case, your best bet would be to include with your executable a config file (appname.exe would have appname.exe.config) that includes binding redirect information for VISA versions.
Where it refers to the VISA assembly in your config file you would include a line as follows:
<bindingRedirect
oldVersion="old assembly version"
newVersion="new assembly version"/>
The following documentation discusses this:
