You must keep the assembly version the same, but change the file version. See

Subject: how to alwyas overwrite GAC assembly in fresh setup
It looks like if we want to specify an install for GAC assembly dll, we have to
use Assembly='.net' in the <File> element, which will require KeyPath has to be
set as "yes" (otherwise we'll have a build error when running candle.exe). Then
this way, if GAC assembly has been left behind, then another fresh install wont
overwrite that dll. How can we ensure the GAC assembly can always be
overwritten?
Below is just an example.
Thanks,
Fei
