You have rightclicked -> Build Solution with ....
Change back to VC10
Click only project Shareaza,
Try using SSE3 and set Properties-> C/C++-> Optimizations to Highest Optimizations (/O3) manually.
After finishing a succeed build, change all projects manually
You can mix VC10 and composer builds if one of the projects not compile properly.
MediaLibraryBuilder and MediaImageServices causes problems sometimes,
especially when using Intel optimizied headers.
I'm not on that high level. Sometimes it works, sometimes not.
