I wonder if someone might have the answer for me.

Win 7 (64 bit) is showing me that I need...
Security Update for Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package (KB2467175)

...but the install always fails, so it keeps showing up.

Anyone know how to fix this?

Have you tried downloading it separately, outside of Windows Update? The file should be somewhere in Microsoft's site.

I'd give you a link, but my ISP is blocking Microsoft tonight.

Here you go, a direct download of that update.

Also, is that the only update you miss? I just had a bunch of updates that kept failing until I decided to try installing them one by one, upon which they all fell in place nicely.

You can also also go by the reference KB246175 which refers to Knowledge Base article 264175

Thank you... all of you... I'll do it.

Yes. That is the only file that is failing on me.

Now that I am on the site, I have this:

"The links in this section correspond to separate files available in this download. Download the files most appropriate for you."

vcredist_IA64.exe
6.3MB

vcredist_x64.exe
3.0MB

vcredist_x86.exe
2.6MB

I'm running Win 7 64 Ultimate (weirdly, that is what the university bookstore sells) So which one is it, or do I load all three in sequence?

Only one:

vcredist_x64.exe
3.0MB

That's the one I'd have guessed. Thank you :-)

I wonder why the MS site doesn't clarify the difference? Or maybe it does and I'm too dense to understand it ;-)

All you all were spot on. My machine is properly updated with no hitches.

Thanks all around :-)

x86 = 32-bit file system (based on the chips being 80x86 where "x" is the number of the level (speed/power) of the CPU - 80486 etc. Pentiums changed that, but they were 80586s)

x64 = 64-bit file system.

No idea what the IA64 is.... Itanium? was that a completely different architecture system? IIRC, servers or something, wasn't it?

Edit : I just put Win7 Ultimate (32-bit) back on this system a couple days ago, and that file failed too, for me. I think it came after something that *needed* a reboot, before that would install - it went on the fine the second round of updates.

Yes, IA64 was Intel's first foray into 64-bit computing, sucked donkey balls though as it didn't run x86 applications natively but had to emulate them with a heavy performance loss. AMD's idea is known by a few names: x64, x86_64, and AMD64, rather than build a complete new architecture, they "merely" extended the existing x86 into 64-bits, intel saw that it was much better than their try and has now licensed it for just about all of their modern 64-bit CPUs.

Funny how I always just accepted the X as just that and never considered it would have a numerical value even though after I read this it's obvious.

Ditto. I learnt something today. thanks GOG! (And Mangakai)

It depends on the app. If the app was made with Visual C++ and is a 32bit app, it would require Visual C++ 2005's redistributable vcredist_x86.exe.

If it was made with Visual C++ 2010 and its a 64bit app, it would require Visual C++ 2010's redistributable vcredist_x64.exe.

Devs can deal with this by integrating the required dlls in their app or the installer, but most just install the redistributable packages.

Yeah :P
TBH about it, most people dropped the "80" from the front when talking about CPUs, and just labelled them by the last 3 digits - 286, 386, 486...and as I said, because Intel couldn't copyright/register trademark a number, they named their 586 CPU the "Pentium", which they could copyright/Trademark.
