Need some help with SDR Sharp

[n4yek]

Hi all,
I have been fighting with an install on one of my computers.

Computer 1 is a desktop Dell running XP home service pack 3, pentium 4 CPU 3.0GHz. 1.5 GB RAM.
I installed SDR Sharp from here: http://sdrsharp.com/downloads/sdr-install.zip
It installed good and then I installed a plugin from here:
**SDR# Plugins
This installed good.

Computer 2: Laptop HP Compaq Presario C500 running Windows Vista Home Basic, Intel Celeron M CPU 1.73 GHz, 1 GB RAM
Now I wanted to do all of that install onto my laptop
SDR Sharp Installed ok but when I went to install the Scanner plugin from **SDR# Plugins I get an error (I attached image sdr_error.zip in case image is fuzzy)

Anyone have any ideas?
Thanks

Do you have the .NET 3.5 framework installed on your Vista machine?

I have 4.0 on both of my machines

You still need the previous versions, as they're not cumulative.

.NET 2.0, 3.5, and 4.0 are distinct versions and as just noted above, you have to have all of them (or at least the ones you specifically need) to make stuff functional. Just because you have the latest version (based on the version number) doesn't mean it'll support the older version functionality, unfortunately.

Same is true with something like DirectX - there are plenty of programs out there that were written long ago using DirectX 9 and 10 aspects, and even with DirectX 11.(whatever) available nowadays, if you install the latest you'll end up with all the libraries for the older versions as well.

I will give that a shot, my desktop has 2.0, 3.0, 3.5, and 4.0....my laptop only shows 2.0, 3.0 & 4.0
I will let you all know.

Every one of you were spot on, that was my problem. I didn't realize that .Net Framework was NOT cumulative in its update.
Thanks guys.

Excellent, glad to hear.

Just to be clear: the .NET frameworks are cumulative in functionality, unless Microsoft deprecated a feature that was present in a previous version.

But as others noted, the versions are separate and specific. .NET executables typically target a specific version of the framework, which was your case.

Which version did the trick,,was it the 3.5?

Yes, version 3.5 solved my issue. The main program, SDR Sharp, worked fine without it but when I tried to install the "Frequency Manager + Scanner" plugin, it didn't want to install.
