Bug Description
When the previous Inkscape version was not uninstalled, the installer takes a very long time to finish (i.e. some minutes on my machine instead of few seconds.)
The behavior seems to depend on the presence of the file "Uninstall.dat":
a) if present the installation is slow
b) if deleted the installation is fast
Installation is also fast if "Uninstall.dat" is present but emptied out (all lines deleted), but it seems we really need to avoid this case as NSIS seems not to add any files to the file in this case (probably detecting them as already present) and consequently won't uninstall them either in future.
This issue seems not to be unheard of in the NSIS community:

/further investigation - also regarding a solution - necessary, though.
Educated guess:
NSIS might try to compare previously installed files to the new files which are to be installed in scenario a) above which might take a lot of time.
