ASP.NET Atlas April CTP Installation Error

It was nice to know I wasn't the only one having problems installing Atlas April CTP due to cabinet file '_28942B4D9DE730210E7C27BD4FBAD377' corrupt.

I originally downloaded Atlas and did "Save As" (which is my habit, to install on multiple PCs). But as with quite a few others, it didn't work: "The cabinet file '_28942B4D9DE730210E7C27BD4FBAD377' required for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package."

I tried again, in both IE and FF, from my desktop and laptop (so four times) - clearing browser cache, etc (after the first time it broke, and I started googling for answers).

Then I noticed one of the comments on ASP.NET Atlas forum about the Publisher being 'Microsoft' versus 'Unknown', and it seemed like the versions I downloaded [Save As] and 'double-clicked' on were 'Unknown Publisher.
While not believing it would work , I tried again (with IE) BUT clicked [Run] instead... and the first dialog that appeared showed Publisher: Microsoft! The install worked fine from that point.

I don't know how/why the authenticode/whatever process would be different for a saved versus 'run straight away' install^, but after four failures across browsers/pcs and one success, I'd encourage others to at least give it a go -- click [Run] when you download!

^ actually, another post makes an interesting point about the effect of security/permissions in your IE 'downloads' folder versus your /My Documents/, /Desktop/ or wherever you might be placing the file when you [Save As]. I don't know enough about it to comment - but sounds feasible...?

Searcharoo v3 is LIVE

Ok, maybe not ALL CAPS exciting, but a new version of my 'basic' C# search engine and web spider Searcharoo is now 'ready'.

There's a pile of stuff I still wanted to add to it: creating interfaces and plug-ins for the Word and Number Normalization, a UK/Australian version of the stemmer, at least putting the 'language/culture' into the Stop/Go/Stemmer/Stopper interfaces so they could be language-specific and a lot more. They'll all have to wait for the next version...

'Support' and 'thanks' emails trickle in fairly regularly, hopefully that will continue.

I think the old articles are still worth reading...
Searcharoo: C# File system indexer and search (version 1)
Searcharoo: C# Search Engine and Web Spider (version 2)
