I installed V6.2.25 today. I used advanced installation to install as service (5.10.45 was also a service installation).
The migration was smooth but required a reboot of my machine.

After reboot I first got the message:
BOINC can't access Internet - check network connection or proxy configuration.

So I checked the HTTP-Proxy configuration. It looked OK but I confirmed it anyway. After that the "Update Project" worked as expected.

After the above actions I wanted to remove the <force_auth>ntlm</force_auth> tag from my cc_config.xml, but discovered that it wasn't there anymore. It must have been removed by either the installation routine or by confirming of the Proxy config.
Proxy identification works as expected in my configuration.

No, it was at the default location C:\Program Files\Boinc
I forgot to mention that I am using XPpro/32.

The cc_config.xml definately was replaced, because my log_flag <checkpoint_debug> was also gone. <checkpoint_debug> and <force_auth> were the only modifications I had in my cc_config.xml.

WCG is quite conservative is making sure the user gets the resource needed when using the computer. This is defined with profile preference pre-sets of which there are 4 + a "Custom". Please visit, after the momentary statistics update your My Grid > Device Manager > Device Profile to see the associated profile with your computer and change if need be to one of your choice described in this FAQ:
Website Device Profile & Local Preferences Information Rev. Aug 1, 2008

Make sure to force a communication between the server and the client for the changes to take effect and look in the message log near the beginning as to which of the 4 standard device profiles is associated (default/home/school/work), as that is the one that would have to be changed.

I upgraded from 6.2.19 the day the request was posted on a XP Pro SP3 32bot on a Core2Quad Q6600 and 3.5 GB of RAM(4 physical) and have seen no problems whatsoever. :)

We have no problem with that, gretchch, so please don't take what follows as a negative comment for you.

However, this Windows installer is meant to be run without taking any particular precaution**, even when upgrading from a 5.xx version and/or when going from a normal user installation to a service installation.
No need to empty the task list, no need to uninstall, you can even launch the installer without stopping Boinc. The installer will take care of everything after first stopping Boinc if necessary.

** With this 6.2.25 beta version there are a few cases where the cc_config.xml file (where you can ask for logging the checkpoints in the message list) can be lost. So if you have a very personalized cc_config.xml file that could be worth saving a copy of it.
The next version 6.2.26 is supposed to have fixed this problem.
Also if you have tasks in "Ready to report" status it could make sense to force an Update from the project tab to make sure you won't lose completed tasks in case any WU would get lost (which has never been reported yet since we are testing this WCG installer).

Cheers. Jean.
