The (apparently innocuous) version changes in the .sln and .vcproj files in the 1_50 distribution cause VC8 (VS 2005) to choke when loading them. However, you can edit them by hand in order to build, as there appears to be nothing substantive. For the .sln files, change Version 10.00 in 1st line to Version 9.00. For the .vcproj files, change the Version attribute from “9.00” to “8.00”. Also note that for those of us without the dshow.h file, you can comment out JUCE_USE_CAMERA in line 68 of juce_AppConfig.h.
