- In VC++ 2010, go to 'Project' menu, 'Properties'
- Go to (unfold) 'Configuration properties', 'C/C++', 'General'
- On the right, in the 'Additionnal include directories' field, click on the drop-down arrow, select 'Modify'
- Click on 'New line' button, click on the '...' button. Browse to the folder where the Quicktime SDK is installed, subfolder CIncludes. The default is: C:\Program Files\QuickTime SDK\CIncludes . Click OK to save.
Now the project should compile (not whitout a few warnings, but it should work). Make a copy of the project folder (usually C:\Documents and Settings\username\My Documents\Visual Studio 2010\Projects\IsadoraBase) and place it somewhere safe, just in case.
**BONUS: LAUNCH ISADORA AFTER COMPILING**
- If you want Isadora to launch every time you click on the debug button, go to 'Project' menu, 'Properties'. Go to (unfold) 'Configuration properties', 'Debugging'. In the 'Command' field, click on the drop-down arrow, select 'Browse' and go select your Isadora executable file in your installation folder. Click OK to save.
