Microsoft has posted a support article regarding some applications that have been found not to work when a Vista computer is upgraded to Vista SP1. The list is pretty small at this point, but an update like this isn’t expected to break as many apps like XP SP2 did.
The good news is that almost all of the programs that have been broken already have updated versions out that let them function normally. There are a few security apps listed, such and BitDefender and Zone Alarm, so make sure you are running a compatible version before upgrading if you want to avoid any issues.
Programs that are blocked from starting after you install Vista SP1:
- BitDefender AV or Internet Security 10 (2008 or later is supported)
- Fujitsu Shock Sensor 22.214.171.124
- Jiangmin KV Antivirus 10 or 2008 (supported versions now available)
- Trend Micro Internet Security 2008 (16.1 or later is supported)
- Zone Alarm Security Suite 7.1 (126.96.36.199 or later is supported)
Programs that do not run after you install Vista SP1:
- Iron Speed Designer 5.0.1 (5.0.2 or later is supported)
- Xheo Licensing 3.1 (3.1 R17024 or later is supported)
- Free Allegiance 2.1
Programs that have a loss of functionality after you install Vista SP1:
- New York Times Reader 1 (supported version now available)
