Could anyone tell me why while I was in my bootcamp, I've tried to install Visual Studio express, but SQL server compact 4.0 wasn't able to install and the Manager too. The rest of Visual Studio express was well installed though. So I made hypothesis about it: 1. I have Mysql server on my mac main partition 2. A software in my Windows partition is using SQL server type. 3. The architecture of the code in a bootcamp partition is not the same than a standard Windows partition. So does someone have a cue on what's happening? Thank you very much.
