@martonmiklos said in Qt Installer Framework: Spaces in target paths (Windows7-64): @Peter.Chorn How did you managed to import the Dir component? In QIF 3 dynamic page example, there is the following definition (installscript.js): var Dir = new function () { this.toNativeSparator = function (path) { if (systemInfo.productType === "windows") return path.replace(/\//g, '\\'); return path; } };
