Word of the Day: ptarmic - substance causing sneezing - Sheesh! That pepper is really ptarmic, man!
RED-FACED executives at Microsoft have sheepishly explained that the reason that they have pulled Vista SP1 from distribution is because it reacts badly with some important third party applications.
According to CRN, on SP1's kill list are products from Trend Micro, Zonelabs, BitDefender, and Novell.
Vole has said that some applications may experience a loss of functionality after you install Windows Vista SP1. This is spin for 'they will not work at all'.
Trend Micro Internet Security 2008, Zone Alarm Security Suite 7.1, and BitDefender's AV and Internet Security products will not actually start, which in technical terms means they are 'completely buggered'.
The problem is that SP1 blocks these programs from starting after you install Windows Vista SP1.
A spokesman for Trend Micros said that there are some workarounds for the Vista SP1 compatibility problem which are being distributed through Trend's auto update service.
BitDefender also offers a free upgrade that fixes the problem.
Vole claims that there is a supported version of Zone Alarm Security Suite (7.1.218.0 or a later version) available.
However Novell's ZCM Agent 10.01 breaks completely and will never be supported in Vista, dispite Novell's recent love in with Microsoft over Open Sauce. µ

Can we get a source on that as nothing is mentioned in the original article?

"I pulled it out of my own arse for the lulz and page hits" will be accepted as a response.

My zboard z-engine also completely fails to load under the RTM SP1. It worked fine under most previous pre-releases so perhaps MS changed something last minute that is conflicting with certain 3rd party apps?

Ultimately this either boils down to a lacklustre communication to 3rd party developers from MS about the SP1 updates OR 3rd party developers not getting their asses in gear and coding their products correctly for Vista.
From the original article:

""For reliability reasons, Microsoft blocks these programs from starting after you install Windows Vista SP1," according to the article, which notes this step was taken with the consent of the affected vendors."
I've read http://support.microsoft.com/kb/935796 and while I did skim some parts of it, I also do not see where this OR the original article states that SP1 was pulled. I'd also like to see the source for this, please.
"with the consent of the affected vendors"

yeah, right.

"we are going to break your program with SP1, is that OK with you?"

"uh, no. Why are you doing that?"

"More importantly, either it is OK with you or we will claim the problem is your fault and not offer you any help in fixing -your- problem. Now is it OK with you?"

"grumblelinuxgrumble... Alright fine"
So whats the big difference between Service pack 1 v.744 and gold? I'm running Vista Ultimate 64 bit/SP1 V.744 and Trend Micro Internet Security Pro 2008 64 bit version. They've been running just fine together for the last month so whats up? Could it be that just the 32bit version is affected by Sp1 or is there a bigger change going on here?
I agree with the other couple posts about this. Software developers need to conform to the OS, NOT the other way around. Just ask any MAC owner. I actually applaud M$ for doing this, which is very rare for me.
Is it SP1 that's been pulled or a Pre-SP1 update that's being pulled, I've read this from many sources and it suggests that it's just a Pre-SP1 update that is cause the problems not SP1.

So what is it?
I've been running Trend Micro Internet Security 2008 for several weeks now. Last night I downloaded and installed Vista SP1 (32-bit) from MSDN and it installed just fine. Trend still works just fine, no issues here at all.
This might be a problem if these programs were in any way useful.
If it stops ZoneAlarm from running, that's an advantage, isn't it?
"However Novell's ZCM Agent 10.01 breaks completely and will never be supported in Vista, dispite Novell's recent love in with Microsoft over Open Sauce"

Yeah, but if you checked MS or Novell you would find that ZCM 10.1.0 resolves the issue.

You don't expect programmers to code for future changes by other companies do you ? Isn't that why they test compatability - so they can fix things that don't work.
