I was fiddling with a batch file to call MSBuild to build my project. Something went wrong because now when I go into XE2 and choose File | New | VCL Forms Application and click 'Build' (or Run) I get the following immediate error:
Checking project dependencies...

I've done a reinstall using 'Repair', tried again using 'Modify' and checked that the *.targets files are all the same as a known good machine all to no avail. I get the same error if I call MSBuild directly with my project *.dproj file (its an empty project). Where might I look?
