When I install SP3, the machine will only boot in safe mode. It boots well, when I do the built in recovery included with the "F10" key at the time of booting. I have tried using a drive update routine. That seems to have no effect, though some drivers continue to show as out of date. I have read some about boot problems coming from installing the wrong version of .netFramework. The recovered machine show the .netFramework as version 2.2. I have read some commentaries on upgrading problems. I am now convinced that my problem is related to the .netframework upgrade.
I need to know how to install the upgrade safely without causing the regular boot mode to fail. I am somewhat of the opinion that if I can get a good working version of Windows Installer 3 plus and use it to install my .netFramework upgrade, I think I can get the machine fixed. I wonder if you can help me identify a valid source for Windows Installer versions so i can proceed to see if the .netframwork can be installed and return return the system to being an S3 machine.
