I would say somewhere between 'negligible' and 'not at all', but I
don't know anything about your laptop and I'm not aware of any
benchmarks that have been done. Personally, I don't understand the
hesitation if doing so enables another program that you want to use.
I'll agree, although I'll also have to note that the comment by "dbdblocker"
about update speed (or rather the lack thereof) is valid. Some time back I
formally complained to the MS account team responsible for my POE about how
long updates take but (unsurprisingly) got nowhere.
As a practical matter, however, like it or not more and more applications
are being written in .NET, and versions 2/3/3.5 are included in Windows 7.
..NET version 4 is not part of Windows 7 but can be installed as a free
update.
By any chance is your application rather old, and is trying to install 1.x?
..NET v1.x isn't supported on Windows 7 but there are several articles on
various websites (including Microsoft's pseudo-newsgroups) that report
success at installing it. I've not tried it (and don't plan to do so) but
search Google for "windows 7 net framework 1.1" and you'll find suggested
ways to force-fit 1.1 onto Win7.
Assuming that your application is trying to install .NET 1.x a better
solution would be to get a more recent version of the application that's
been recompiled with a more recent version of .NET.
